What happened 1900 AD

After his exile, Lenin settled in Pskov in early 1900. There, he began raising funds for a newspaper, Iskra ("Spark"), a new organ of the Russian Marxist party, now calling itself the Russian Social Democratic Labour Party (RSDLP).

In 1900, Einstein passed the exams in Maths and Physics and was awarded the Federal Polytechnic teaching diploma.

Picasso made his first trip to Paris, then the art capital of Europe, in 1900. There, he met his first Parisian friend, journalist and poet Max Jacob, who helped Picasso learn the language and its literature

As football began to increase in popularity, it was contested as an IOC-recognised Olympic sport at the 1900 and 1904 Summer Olympics, as well as at the 1906 Intercalated Games, before becoming an official FIFA-supervised Olympic competition at the 1908 Summer Olympics.

In 1900 the brothers went to Kitty Hawk, North Carolina, to begin their manned gliding experiments.

The Boxer Rebellion prompted another foreign invasion of Beijing in 1900 and the imposition of unequal treaty terms, which carved away territories, created extraterritorial concessions and gave away trade privileges. Under internal and external pressure, the Qing court began to adopt some of the reforms.

In 1900, Curie became the first woman faculty member at the École Normale Supérieure, and her husband joined the faculty of the University of Paris.

The British government took these defeats badly and with the sieges still continuing was compelled to send two more divisions plus large numbers of colonial volunteers. By January 1900 this would become the largest force Britain had ever sent overseas, amounting to some 180,000 men with further reinforcements being sought.

In the second phase, after the number of British troops was greatly increased under the command of Lord Roberts, the British launched another offensive in 1900 to relieve the sieges, this time achieving success. After Natal and the Cape Colony were secure, the British army was able to invade the Transvaal, and the republic's capital, Pretoria, was ultimately captured in June 1900.

In 1900, Eastman took mass-market photography one step further with the Brownie, a simple and very inexpensive box camera that introduced the concept of the snapshot. The Brownie was extremely popular and various models remained on sale until the 1960s.

Tesla lived at the Waldorf Astoria in New York City from 1900 and ran up a large bill.

The Battle of Spion Kop was fought about 38 km (24 mi) west-south-west of Ladysmith on the hilltop of Spioenkop along the Tugela River, Natal in South Africa from 23–24 January 1900. It was fought between the South African Republic and the Orange Free State on the one hand and British forces during the Second Boer War campaign to relieve Ladysmith. It resulted in a Boer victory. The battle, collectively with its location at a hill, has gone down in British football lore as the namesake of a common British term for single-tier terraces and/or stands at football stadia.

British troops captured the summit by surprise during the early hours of 24 January 1900, but as the early morning fog lifted they realised too late that they were overlooked by Boer gun emplacements on the surrounding hills. The result was 350 men killed and nearly 1,000 wounded and a retreat across the Tugela River into British territory. There were nearly 300 Boer casualties.

In January 1900, Churchill briefly rejoined the army as a lieutenant in the South African Light Horse regiment, joining Redvers Buller's fight to relieve the Siege of Ladysmith and take Pretoria. He was among the first British troops in both places. He and his cousin, the 9th Duke of Marlborough, demanded and received the surrender of 52 Boer prison camp guards. Throughout the war, he had publicly chastised anti-Boer prejudices, calling for them to be treated with "generosity and tolerance", and after the war, he urged the British to be magnanimous in victory.

Roberts launched his main attack on 10 February 1900 and although hampered by a long supply route, managed to outflank the Boers defending Magersfontein. Field Marshal Frederick Sleigh Roberts, 1st Earl Roberts was a British Victorian era general who became one of the most successful British military commanders of his time. Born in India to an Anglo-Irish family, Roberts joined the East India Company Army and served as a young officer in the Indian Rebellion during which he won a Victoria Cross for gallantry. He was then transferred to the British Army and fought in the Expedition to Abyssinia and the Second Anglo-Afghan War, in which his exploits earned him widespread fame. Roberts would go on to serve as the Commander-in-Chief, India before leading British Forces to success in the Second Boer War. He also became the last Commander-in-Chief of the Forces before the post was abolished in 1904.

In Natal, the Battle of the Tugela Heights, which started on 14 February was Buller's fourth attempt to relieve Ladysmith. The losses Buller's troops had sustained convinced Buller to adopt Boer tactics "in the firing line—to advance in small rushes, covered by rifle fire from behind; to use the tactical support of artillery; and above all, to use the ground, making rock and earth work for them as it did for the enemy." Despite reinforcements his progress was painfully slow against stiff opposition.

On 14 February, a cavalry division under Major General John French launched a major attack to relieve Kimberley. Although encountering severe fire, a massed cavalry charge split the Boer defenses on 15 February, opening the way for French to enter Kimberley that evening, ending its 124 days' siege.

On 17 February, a pincer movement involving both French's cavalry and the main British force attempted to take the entrenched position, but the frontal attacks were uncoordinated and so were easily repulsed by the Boers. Finally, Roberts resorted to bombarding Cronjé into submission, but it took a further ten precious days, and with the British troops using the polluted Modder River as water supply, there was a typhoid epidemic killing many troops. General Cronjé was forced to surrender at Surrender Hill with 4,000 men.

The Battle of Paardeberg or Perdeberg ("Horse Mountain") was a major battle during the Second Anglo-Boer War. It was fought near Paardeberg Drift on the banks of the Modder River in the Orange Free State near Kimberley. Lord Methuen advanced up the railway line in November 1899 with the objective of relieving the besieged city of Kimberley (and the town of Mafeking, also under siege). Battles were fought on this front at Graspan, Belmont, Modder River before the advance was halted for two months after the British defeat at the Battle of Magersfontein. In February 1900, Field Marshal Lord Roberts assumed personal command of a significantly reinforced British offensive.

On 26 February, after much deliberation, Buller used all his forces in one all-out attack for the first time and at last succeeded in forcing a crossing of the Tugela to defeat Botha's outnumbered forces north of Colenso.

After a siege lasting 118 days, the Relief of Ladysmith was effected, the day after Cronjé surrendered, but at a total cost of 7,000 British casualties. Buller's troops marched into Ladysmith on 28 February.

In the third and final phase, beginning in March 1900 and lasting a further two years, the Boers conducted a hard-fought guerrilla war, attacking British troop columns, telegraph sites, railways, and storage depots. To deny supplies to the Boer guerrillas, the British, now under the leadership of Lord Kitchener, adopted a scorched earth policy. They cleared whole areas, destroying Boer farms and moving the civilians into concentration camps.

Battle of Poplar Grove. was an incident on 7 March 1900 during the Second Boer War in South Africa. It followed on from the Relief of Kimberley as the British Army moved to take the Boer capital of Bloemfontein. The Boers were demoralized following the surrender of Piet Cronjé at the Battle of Paardeberg.

After a succession of defeats, the Boers realized that against such overwhelming numbers of troops, they had little chance of defeating the British and so became demoralized. Roberts then advanced into the Orange Free State from the west, putting the Boers to flight at the Battle of Poplar Grove and capturing Bloemfontein, the capital, unopposed on 13 March with the Boer defenders escaping and scattering. Meanwhile, he detached a small force to relieve Baden-Powell.

On 15 March 1900, Lord Roberts proclaimed an amnesty for all burghers, except leaders, who took an oath of neutrality and returned quietly to their homes. It is estimated that between 12,000 and 14,000 burghers took this oath between March and June 1900.

British observers believed the war to be all but over after the capture of the two capital cities. However, the Boers had earlier met at the temporary new capital of the Orange Free State, Kroonstad, and planned a guerrilla campaign to hit the British supply and communication lines. The first engagement of this new form of warfare was at Sanna's Post on 31 March where 1,500 Boers under the command of Christiaan de Wet attacked Bloemfontein's waterworks about 37 kilometres (23 mi) east of the city, and ambushed a heavily escorted convoy, which caused 155 British casualties and the capture of seven guns, 117 wagons, and 428 British troops.

According to one story, the use of the complete phrase hot dog in reference to sausage was coined by the newspaper cartoonist Thomas Aloysius "Tad" Dorgan around 1900 in a cartoon recording the sale of hot dogs during a New York Giants baseball game at the Polo Grounds.

For the 1900 Exposition Universelle, the lifts in the east and west legs were replaced by lifts running as far as the second level constructed by the French firm Fives-Lille. These had a compensating mechanism to keep the floor level as the angle of ascent changed at the first level, and were driven by a similar hydraulic mechanism to the Otis lifts, although this was situated at the base of the tower. Hydraulic pressure was provided by pressurized accumulators located near this mechanism. At the same time the lift in the north pillar was removed and replaced by a staircase to the first level. The layout of both first and second levels was modified, with the space available for visitors on the second level. The original lift in the south pillar was removed 13 years later.

Du Bois was primary organizer of The Exhibit of American Negroes at the Exposition Universelle held in Paris between April and November 1900, for which he put together a series of 363 photographs aiming to commemorate the lives of African Americans at the turn of the century and challenge the racist caricatures and stereotypes of the day.

Co-organised a secret workers' mass meeting for May Day 1900, at which he successfully encouraged many of the men to take strike action. By this point, the empire's secret police—the Okhrana—were aware of Stalin's activities within Tiflis' revolutionary milieu. They attempted to arrest him in March 1901, but he escaped and went into hiding, living off the donations of friends and sympathizers.

From late May 1900, the first successes of the Boer guerrilla strategy were at Lindley (where 500 Yeomanry surrendered), and at Heilbron (where a large convoy and its escort were captured) and other skirmishes resulting in 1,500 British casualties in less than ten days.

The Relief of Mafeking on 18 May 1900 provoked riotous celebrations in Britain, the origin of the Edwardian slang word "mafficking".

On 28 May, the Orange Free State was annexed and renamed the Orange River Colony.

Roberts was forced to halt again at Kroonstad for 10 days, due once again to the collapse of his medical and supply systems, but finally captured Johannesburg on 31 May and the capital of the Transvaal, Pretoria, on 5 June.

Hepburn's mother, Baroness Ella van Heemstra (12 June 1900 – 26 August 1984), was a Dutch noblewoman. She was the daughter of Baron Aarnoud van Heemstra, who served as Mayor of Arnhem from 1910 to 1920 and as Governor of Dutch Suriname from 1921 to 1928, and Baroness Elbrig Willemine Henriette van Asbeck (1873–1939).

In 1900, Woodson was selected as the principal of Douglass High School.

Tesla had an agreement with the editor of The Century Magazine to produce an article on his findings. The magazine sent a photographer to Colorado to photograph the work being done there. The article, titled "The Problem of Increasing Human Energy", appeared in the June 1900 edition of the magazine. He explained the superiority of the wireless system he envisioned but the article was more of a lengthy philosophical treatise than an understandable scientific description of his work, illustrated with what were to become iconic images of Tesla and his Colorado Springs experiments.

Born in Wegeleben (now in Saxony-Anhalt) in the Kingdom of Prussia in the German Empire, Bormann was the son of Theodor Bormann (1862–1903), a post office employee, and his second wife, Antonie Bernhardine Mennong.

The executors of the will, Ragnar Sohlman and Rudolf Lilljequist, formed the Nobel Foundation to take care of the fortune and to organise the awarding of prizes.the Nobel Foundation's newly created statutes were promulgated by King Oscar II.

In July 1900, at the age of eight, Broz entered primary school at Kumrovec, but only completed four years of school, failing the 2nd grade then graduating in 1905.

As Roberts's army occupied Pretoria, the Boer fighters in the Orange Free State retreated into the Brandwater Basin, a fertile area in the north-east of the Republic. This offered only temporary sanctuary, as the mountain passes leading to it could be occupied by the British, trapping the Boers. A force under General Archibald Hunter set out from Bloemfontein to achieve this in July 1900. The hardcore of the Free State Boers under De Wet, accompanied by President Steyn, left the basin early. Those remaining fell into confusion and most failed to break out before Hunter trapped them.

In 1900, Du Bois attended the First Pan-African Conference, held in London from July 23 to 25.

In Denmark by 1900, there were about 2500 windmills for mechanical loads such as pumps and mills, producing an estimated combined peak power of about 30 MW. The largest machines were on 24-meter (79 ft) towers with four-bladed 23-meter (75 ft) diameter rotors.

In 1901, after the Boxer Rebellion started, Tang Caichang and Tan Sitong of the previous Foot Emancipation Society organised the Independence Army. The Independence Army Uprising was planned to occur on 23 August 1900. Their goal was to overthrow Empress Dowager Cixi to establish a constitutional monarchy under the Guangxu Emperor. Their plot was discovered by the governor general of Hunan and Hubei. About twenty conspirators were arrested and executed.

The set-piece period of the war now largely gave way to a mobile guerrilla war, but one final operation remained. President Kruger and what remained of the Transvaal government had retreated to eastern Transvaal. Roberts, joined by troops from Natal under Buller, advanced against them, and broke their last defensive position at Bergendal on 26 August.

By September 1900, the British were nominally in control of both Republics, with the exception of the northern part of Transvaal. However, they soon discovered that they only controlled the territory their columns physically occupied. Despite the loss of their two capital cities and half of their army, the Boer commanders adopted guerrilla warfare tactics, primarily conducting raids against railways, resource and supply targets, all aimed at disrupting the operational capacity of the British Army. They avoided pitched battles and casualties were light.

Roberts declared the war over on 3 September 1900; and the South African Republic was formally annexed.

Churchill rented a flat in London's Mayfair, using it as his base for the next six years.

Churchill stood again as one of the Conservative candidates at Oldham in the October 1900 general election, securing a narrow victory to become a Member of Parliament (MP) at age 25.

The brothers flew the glider for only a few days in the early autumn of 1900 at Kitty Hawk. In the first tests, probably on October 3, Wilbur was aboard while the glider flew as a kite not far above the ground with men below holding tether ropes. Most of the kite tests were unpiloted, with sandbags or chains and even a local boy as ballast.

Heinrich Luitpold Himmler was born in Munich on 7 October 1900 into a conservative middle-class Roman Catholic family. His father was Joseph Gebhard Himmler (17 May 1865 – 29 October 1936), a teacher, and his mother was Anna Maria Himmler (née Heyder; 16 January 1866 – 10 September 1941), a devout Roman Catholic. Heinrich had two brothers, Gebhard Ludwig (29 July 1898 – 22 June 1982) and Ernst Hermann (23 December 1905 – 2 May 1945).

On 8 October 1900, Sun Yat-sen ordered the launch of the Huizhou Uprising. The revolutionary army was led by Zheng Shiliang and initially included 20,000 men, who fought for half a month. However, after the Japanese Prime Minister prohibited Sun Yat-sen from carrying out revolutionary activities on Taiwan, Zheng Shiliang had no choice but to order the army to disperse. This uprising therefore also failed. British soldier Rowland J. Mulkern participated in this uprising.

In the same month, Churchill published Ian Hamilton's March, a book about his South African experiences, which became the focus of a lecture tour in November through Britain, America, and Canada. MPs were unpaid and the tour was a financial necessity. In America, Churchill met Mark Twain, President McKinley, and Vice President Theodore Roosevelt; he did not get on well with Roosevelt. Later, in spring 1901, he gave more lectures in Paris, Madrid, and Gibraltar.

After having conferred with the Transvaal leaders, Christiaan de Wet returned to the Orange Free State, where he inspired a series of successful attacks and raids from the hitherto quiet western part of the country, though he suffered a rare defeat at Bothaville in November 1900.

In December 1900, De la Rey and Christiaan Beyers attacked and mauled a British brigade at Nooitgedacht. As a result of these and other Boer successes, the British, led by Lord Kitchener, mounted three extensive searches for Christiaan de Wet, but without success.

In the first decade of the new century, Du Bois emerged as a spokesperson for his race, second only to Booker T. Washington.
