Question: How many parties made up the One Israel alliance the year it won the Knesset? Passage 1:The Duchy of Prussia was a duchy in the eastern part of Prussia from 1525–1701. In 1525 during the Protestant Reformation, the Grand Master of the Teutonic Knights, Albert of Hohenzollern, secularized the Prussian State of the Teutonic Order, becoming Albert, Duke in Prussia. His duchy, which had its capital in Königsberg (Kaliningrad), was established as a fief of the Crown of Poland, as had been Teutonic Prussia since the Second Peace of Thorn in October 1466. This treaty had ended the War of the Cities or Thirteen Years' War and provided for the Order's cession of its rights over the western half of its territories to the Polish crown, which became the province of Royal Prussia, while the remaining part of the Order's land became a fief of the Kingdom of Poland (1385–1569). In the 17th century King John II Casimir of Poland submitted Frederick William to regain Prussian suzerainty in return for supporting Poland against Sweden. On July 29, 1657, they signed the Treaty of Wehlau in Wehlau (Polish: Welawa; now Znamensk), whereby Frederick William renounced a previous Swedish-Prussian alliance and John Casimir recognised Frederick William's full sovereignty over the Duchy of Prussia. Full sovereignty was a necessary prerequisite for upgrading the Duchy to Kingdom of Prussia in 1701.
 Passage 2:The Meimad movement was founded on 1 June 1988 by Rabbi Yehuda Amital, and included former National Religious Party Knesset member Yehuda Ben-Meir. It contested the November 1988 Knesset elections, receiving 0.7% of the vote and failing to cross the 1% electoral threshold. Eleven years later, a political arm was established, and joined the One Israel alliance that won the Knesset elections that year. Meimad received one seat, taken by Michael Melchior. It gained a second when Yehuda Gilad replaced Maxim Levy in 2002. Tova Ilan also represented Meimad in the Knesset for a brief spell in 2006, after several other Labour MKs resigned. It attracted moderates among immigrants from the English-speaking world, including Shimon Glick.
 Passage 3:Corry cleared Bermuda on 25 October 1942 for Casablanca to participate in the Moroccan landings, in the screen of the aircraft carrier . She left Casablanca 16 November for Norfolk and Boston, and after overhaul resumed her coastal and Caribbean operations until 13 February 1943, when she sailed on escort duty from Norfolk for north Africa, returning 6 March for operations in the western Atlantic. On 11 August she sailed for Scotland and operated with the British Home Fleet, cruising once to Norway as providing escort for Ranger in the successful Allied air raid on Bodø, Norway in October 1943 (Operation Leader). Corry sailed twice to Iceland to cover the movement of Russia-bound convoys. Returning to Boston on 3 December, Corry sailed on 24 December for escort duty to New Orleans and Panama.
