On 3 June 1991, William was admitted to Royal Berkshire Hospital after being accidentally hit on the forehead by a fellow student wielding a golf club. He suffered a depressed fracture of the skull and was operated on at Great Ormond Street Hospital, resulting in a permanent scar. In a 2009 interview, he dubbed this scar a "Harry Potter scar" and said, "I call it that because it glows sometimes and some people notice it—other times they don't notice it at all".
On June 12, 1991, Boris Yeltsin won 57 percent of the popular vote in the democratic elections, defeating Gorbachev's preferred candidate, Nikolai Ryzhkov, who won 16 percent of the vote. Following Yeltsin's election as president, Russia declared itself independent.
In June 1991, James Gosling, Mike Sheridan, and Patrick Naughton initiated the Java language project. Java was originally designed for interactive television, but it was too advanced for the digital cable television industry at the time. The language was initially called Oak after an oak tree that stood outside Gosling's office. Later the project went by the name Green and was finally renamed Java, from Java coffee, the coffee from Indonesia.
Shakira's debut album, Magia, was recorded with Sony Music Colombia in 1990 when she was only 13 years old.The songs are a collection made by her since she was eight, mixed pop-rock ballads and disco uptempo songs with electronic accompaniment; however, it was hampered by a lack of cohesion in both its recording and the production. The album was released in June 1991 and featured "Magia" and three other singles. Though it fared well on Colombian radio and gave the young Shakira much exposure, the album did not fare well commercially, as only 1,200 copies were sold worldwide.
On 25 June 1991, both Slovenia and Croatia declared independence, which led to a short armed conflict in Slovenia called the Ten-Day War, and an all-out war in Croatia in the Croatian War of Independence in areas with a substantial ethnic Serb population.
On the morning of 26 June, units of the Yugoslav People's Army's 13th Corps left their barracks in Rijeka, Croatia, to move towards Slovenia's borders with Italy.
Despite the confusion and fighting, the YPA nonetheless successfully accomplished much of its military mission. By midnight on 27 June it had captured all of the crossings along the Italian border, all but three crossings on the Austrian border and several of the new crossing points established along Slovenia's border with Croatia.
Further YPA troop movements took place in the early hours of 27 June. A unit of the YPA's 306th Anti-Aircraft Regiment, based in Karlovac, Croatia, crossed the Slovenian border at Metlika.
In the early hours of 27 June the Slovenian leadership was told of the movements of the YPA. The military leadership of the Fifth Military District, which included Slovenia, was in telephone contact with Slovenian president Milan Kučan, telling him that the troops' mission was limited to taking over the border crossings and airport. A meeting of the Slovene presidency was hastily convened at which Kučan and the rest of the members decided on armed resistance.
A few hours later, a column of tanks and armoured personnel carriers of the YPA 1st Armoured Brigade left their barracks at Vrhnika near the Slovenian capital Ljubljana, heading for the airport at Brnik.
The border crossings were a major source of revenue. In addition, by taking control of the borders, the Slovenians were able to establish defensive positions against an expected JLA attack. This meant that the YPA would have to fire the first shot. It was fired on 27 June at 14:30 in Divača by an officer of YPA.
On 28 June 1991, he became head of the Committee for External Relations of the Mayor's Office, with responsibility for promoting international relations and foreign investments.
Additional fighting took place throughout the day. The YPA tank column that had been attacked at Pesnica the previous day was blocked by impromptu barricades of Slovenian trucks at Štrihovec, a few kilometers short of the border with Austria, where it again came under attack by Slovenian TO personnel and Slovenian police. The SFR Yugoslav Air Force mounted two airstrikes in support of the YPA forces at Strihovec, killing four truck drivers. At Medvedjek in central Slovenia, another YPA tank column came under attack at a truck barricade, where air raids killed six truck drivers. Heavy fighting broke out at Nova Gorica on the border with Italy, where the Slovenian Special Forces fired two armburst antitank rockets and fired 700 rounds from infantry weapons. Slovene troops destroyed two YPA T-55 tanks and captured an additional three, plus a BTS-1 racked buldozer. Three YPA soldiers were killed and 16 wounded, among them the commander of the armored column, and 98 surrendered. By the end of the day, the YPA still held many of its positions but was rapidly losing ground. YPA was beginning to experience problems with desertions — many Slovenian members of the YPA quit their units or simply changed sides - and both the troops on the ground and the leadership in Belgrade appeared to have little idea of what to do next.
