Question: How long had Ferdinand I been in power when he defeated Zapolya? Passage 1:Dr. Radek Zelenka is a fictional character of a scientist in the television series Stargate Atlantis, portrayed by David Nykl. He is a member of the original expedition from Earth to the Ancient city of Atlantis in the Pegasus galaxy, which he joined after turning down a job at Masaryk University in his home country Czech Republic. His expertise on Ancient technology is only surpassed by Dr. Rodney McKay, with whom he shares a friendly rivalry. Zelenka's planned one-time appearance in the season 1 episode "Thirty-Eight Minutes" was followed by a recurring role for expository scenes with McKay and the leader of the expedition. Zelenka has since appeared in approximately half of each season's episodes and also appeared in the crossover episode "The Pegasus Project" of Stargate SG-1. The series finale of Atlantis, "Enemy at the Gate", marks his last appearance. For his portrayal of Radek Zelenka, David Nykl was nominated for a 2005 Leo Award in the category "Dramatic Series: Best Supporting Performance by a Male".
 Passage 2:After a spell at Peterborough United, during which he regained fitness playing regularly in the reserves, Lormor moved to Division Three club Chesterfield in December 1994. In partnership with Phil Robinson, Lormor helped Chesterfield to a run of 21 games unbeaten, which would have been 22 had he not missed a penalty. According to the club's website, "the influence of these two on the side cannot be overstated". Robinson and Lormor scored the goals in the 1995 playoff final against Bury that earned the club promotion to Division Two. Injury disrupted his next season, and after a long period playing either out of position in midfield or not playing at all, he asked for a transfer. Lormor did however contribute to Chesterfield's run to the 1996–97 FA Cup semi finals. He scored in the 2nd round against Scarborough but did not play in the tournament later than the 3rd round against Bristol City as his teammates went on to beat the likes of Bolton Wanderers and Nottingham Forest en route to a semi final against Middlesbrough at Old Trafford. In November 1997, Lormor joined Preston North End in part-exchange for David Reeves.
 Passage 3:Pavle Bakić had a timar, as did his father, and held great estates around Venčac in Šumadija called "Bakić's land". He was highly viewed of by the Ottoman Empire, and had the rights to collect taxes (kharaj) from his people. In talks with Pál Tomori and Louis II of Hungary, he left his land with his family, five brothers (including Petar Bakić), and a great number of Serbs, into Hungary, and in return he received the town of Lak among other estates. With his forces he participated in the Battle of Mohács in 1526. When the succession war between Ferdinand I and John Zápolya started, he took the side of Zápolya. After the defeat of Zápolya in the Battle of Tokaj in 1527, he sided with Ferdinand and would stay faithful to him for the rest of his life. In 1528, Ferdinand confirmed Bakić and his brothers' holdings and appointed him the captain of the Serbian infantry, cavalry and river forces. In the defence of Vienna in 1529, Bakić was an important aspect with his cavalry. In charters of 1534, Ferdinand again confirmed Bakić and his brothers' holdings (Lak, Győr, Szombathely, Hédervár and all estates that were part of these towns). The fortress of Győr was administered by his Hungarian ally Count György Cseszneky. A charter dated September 20, 1537, titles him as Despot and called all Serbs to join Bakić as the Serbian Despot. Attempts made by King Ferdinand to push the Ottomans out of Slavonia, with the use of Pavle, were not successful. Bakić did not manage to liberate Osijek from the Ottomans, he then retreated to Đakovo, where he at Gorjani, in a battle against the Ottomans, died (1537). Mehmed-paša sent his son with the head of Bakić to Istanbul.
