IN: Isabella I (Spanish: Isabel, 22 April 1451 - 26 November 1504) reigned as Queen of Castile from 1474 until her death. Her marriage to Ferdinand II of Aragon became the basis for the political unification of Spain under their grandson, Charles I. After a struggle to claim her right to the throne, she reorganized the governmental system, brought the crime rate to the lowest it had been in years, and unburdened the kingdom of the enormous debt her brother had left behind.

At the end of the Reconquista, only Granada was left for Isabella and Ferdinand to conquer. The Emirate of Granada had been held by the Muslim Nasrid dynasty since the mid-13th century. Protected by natural barriers and fortified towns, it had withstood the long process of the reconquista. On 1 February 1482, the king and queen reached Medina del Campo and this is generally considered the beginning of the war for Granada. While Isabella's and Ferdinand's involvement in the war was apparent from the start, Granada's leadership was divided and never able to present a united front. It still took ten years to conquer Granada, however, culminating in 1492. The Spanish monarchs recruited soldiers from many European countries and improved their artillery with the latest and best cannons. Systematically, they proceeded to take the kingdom piece by piece. In 1485 they laid siege to Ronda, which surrendered after only a fortnight due to extensive bombardment. The following year, Loja was taken, and again Muhammad XII was captured and released. One year later, with the fall of Malaga, the western part of the Muslim Nasrid kingdom had fallen into Spanish hands. The eastern province succumbed after the fall of Baza in 1489. The siege of Granada began in the spring of 1491 and at the end of the year, Muhammad XII surrendered. On 2 January 1492 Isabella and Ferdinand entered Granada to receive the keys of the city, and the principal mosque was reconsecrated as a church. The Treaty of Granada was signed later that year, and in it Ferdinand and Isabella gave their word to allow the Muslims and Jews of Granada to live in peace. An uprising by the Moors in 1500 caused the Catholic side to consider that the Moors had violated the Treaty: this gave them a justification for revoking its provisions. See Morisco Revolt. During the war, Isabella noted the abilities and energy of Gonzalo Fernandez de Cordoba and made him one of the two commissioners for the negotiations. Under her patronage, De Cordoba went on to an extraordinary military career that revolutionised the organisation and tactics of the emerging Spanish military, changing the nature of warfare and altering the European balance of power.

IN: Rammstein (German pronunciation: ['RamStaIn]) is a German Neue Deutsche Harte band, formed in 1994 in Berlin. Throughout its existence, Rammstein's six-man lineup has remained unchanged--lead guitarist Richard Z. Kruspe, bassist Oliver "Ollie" Riedel, drummer Christoph "Doom" Schneider, lead vocalist Till Lindemann, rhythm guitarist Paul H. Landers, and keyboardist Christian "Flake" Lorenz. The band helped to found a subgenre within German hard rock and metal that became known as Neue Deutsche Harte. The majority of their songs are in German, but they have also performed songs entirely or partially in other languages including English, Spanish, French, and Russian.

Rammstein's album Mutter was recorded in the south of France in May and June 2000, and mixed in Stockholm in October of that year. During December 2000, Rammstein released an MP3 version of "Links 2-3-4" as a teaser for their new album. 2001 was a busy year for Rammstein, as the band needed to finish off the Sehnsucht Tour ending in January and February with the band playing the Big Day Out festival in Australia and New Zealand and playing some concerts in Japan. January also heralded the shooting of the video for their upcoming single, "Sonne", recorded in Potsdam at Babelsberger Filmstudios from 13 to 15 January 2001. The video was released on 29 January 2001. The single for "Sonne" was released on 12 February 2001 in Europe, featuring an instrumental version of the song, two remixes by Clawfinger and the song "Adios" from the upcoming album. Mutter was released on 2 April 2001, sparking another Rammstein tour through Germany, Austria, and Switzerland. On 14 May, the second single from the album, "Links 2 3 4", was released, along with a video of the single on 18 May. After a tour throughout Europe in June, the band then toured the U.S., Canada and Mexico from June to August 2001. "Ich will", the third single from the album, was released on 10 September 2001 and a Tour edition of the Mutter album (the cover of which is red) was released, featuring alternative artwork and live versions of "Ich will", "Links 2 3 4", "Sonne" and "Spieluhr". From 8 to 12 January 2002, Rammstein traveled to Prague to participate in a minor scene for the film XXX. The band is seen in the opening scene, performing their song "Feuer frei!" in a concert. "Feuer frei!" was released across Europe as the first single from the XXX soundtrack on 14 October 2002. Rammstein released two remixes of the song. Furthermore, the single's track listing included "Du hast" and "Buck dich" cover versions by Battery. The video for the single was edited by Rob Cohen and contains part Rammstein performance at the beginning of the film and part snippets from the film itself.
