In 1815, however, after a number of political and military disputes with the government of Cartagena, Bolívar fled to Jamaica, where he was denied support. After an assassination attempt in Jamaica, he fled to Haiti, where he was granted protection. He befriended Alexandre Pétion, the president of the recently independent southern republic (as opposed to the Kingdom of Haiti in the north), and petitioned him for aid.
In 1905, Marcus moved to Kingston, where he boarded in Smith Village, a working-class neighbourhood. In the city, he secured work with the printing division of the P.A. Benjamin Manufacturing Company. He rose quickly through the company ranks, becoming their first Afro-Jamaican foreman.
Garvey became a trade unionist and took a leading role in the November 1908 print workers' strike. The strike was broken several weeks later and Garvey was sacked. Henceforth branded a troublemaker, Garvey was unable to find work in the private sector. He then found temporary employment with a government printer. As a result of these experiences, Garvey became increasingly angry at the inequalities present in Jamaican society.
In early 1910, Garvey began publishing a magazine, Garvey's Watchman—its name a reference to George William Gordon's The Watchman—although it only lasted three issues. He claimed it had a circulation of 3000, although this was likely an exaggeration. Garvey also enrolled in elocution lessons with the radical journalist Robert J. Love, whom Garvey came to regard as a mentor. With his enhanced skill at speaking in a Standard English manner, he entered several public speaking competitions.
Garvey involved himself with the National Club, Jamaica's first nationalist organization, becoming its first assistant secretary in April 1910. The group campaigned to remove the British Governor of Jamaica, Sydney Olivier, from office, and to end the migration of Indian "coolies", or indentured workers, to Jamaica, as they were seen as a source of economic competition by the established population. With fellow Club member Wilfred Domingo he published a pamphlet expressing the group's ideas, The Struggling Mass.
Garvey arrived back in Jamaica in July 1914. There, he saw his article for Tourist republished in The Gleaner. He began earning money selling greeting and condolence cards which he had imported from Britain, before later switching to selling tombstones.
Also in July 1914, Garvey launched the Universal Negro Improvement Association and African Communities League, commonly abbreviated as UNIA. Adopting the motto of "One Aim. One God. One Destiny", it declared its commitment to "establish a brotherhood among the black race, to promote a spirit of race pride, to reclaim the fallen and to assist in civilizing the backward tribes of Africa".
In August 1914, Garvey attended a meeting of the Queen Street Baptist Literary and Debating Society, where he met Amy Ashwood, recently graduated from the Westwood Training College for Women. She joined UNIA and rented a better premises for them to use as their headquarters, secured using her father's credit. She and Garvey embarked on a relationship, which was opposed by her parents. In 1915 they secretly became engaged. When she suspended the engagement, he threatened to commit suicide, at which she resumed it.
In April 1915, Brigadier General L. S. Blackden lectured to the group on the war effort; Garvey endorsed Blackden's calls for more Jamaicans to sign up to fight for the Empire on the Western Front. The group also sponsored musical and literary evenings as well as a February 1915 elocution contest, at which Garvey took first prize.
Back in Kingston, UNIA obtained Edelweiss Park in Cross Roads, which it established as its new headquarters. They held a conference there, opened by a parade through the city which attracted tens of thousands of onlookers.
In Kingston, Garvey was greeted by supporters. UNIA members had raised $10,000 to help him settle in Jamaica, with which he bought a large house in an elite neighbourhood, which he called the "Somali Court". His wife shipped over his belongings—which included 18,000 books and hundreds of antiques—before joining him.
In Kingston, Garvey was elected a city councillor and established the country's first political party, the People's Political Party (PPP), through which he intended to contest the forthcoming legislative council election. In September 1929 he addressed a crowd of 1,500 supporters, launching the PPP's manifesto, which included land reform to benefit tenant farmers, the addition of a minimum wage to the constitution, pledges to build Jamaica's first university and opera house, and a proposed law to impeach and imprison corrupt judges.
In February 1962, Marley recorded four songs, "Judge Not", "One Cup of Coffee", "Do You Still Love Me?" and "Terror", at Federal Studios for local music producer Leslie Kong. Three of the songs were released on Beverley's with "One Cup of Coffee" being released under the pseudonym, Bobby Martell.
In 1963, Bob Marley, Bunny Wailer, Peter Tosh, Junior Braithwaite, Beverley Kelso, and Cherry Smith were called the Teenagers. They later changed the name to the Wailing Rudeboys, then to the Wailing Wailers, at which point they were discovered by record producer Coxsone Dodd, and finally to the Wailers.
In 1966, Marley married Rita Anderson, and moved near his mother's residence in Wilmington, Delaware in the United States for a short time, during which he worked as a DuPont lab assistant and on the assembly line at a Chrysler plant in nearby Newark, under the alias Donald Marley.
On 3 December 1976, two days before "Smile Jamaica", a free concert organised by the Jamaican Prime Minister Michael Manley in an attempt to ease tension between two warring political groups, Marley, his wife, and manager Don Taylor were wounded in an assault by unknown gunmen inside Marley's home. Taylor and Marley's wife sustained serious injuries but later made full recoveries. Bob Marley received minor wounds in the chest and arm.
Marley received a state funeral in Jamaica on 21 May 1981, which combined elements of Ethiopian Orthodoxy and Rastafari tradition. He was buried in a chapel near his birthplace with his guitar, and the Jamaican Prime Minister Edward Seaga delivered the final funeral eulogy to Marley.
