Question: Jan Zizka z Trocnova a Kalicha (Czech pronunciation: ['jan 'ZISka] ( listen); German: Johann Ziska; English: John Zizka of Trocnov and the Chalice) was a Czech general, a contemporary and follower of Jan Hus, Hussite military leader, and later also a Radical Hussite who led the Taborites. Zizka is held to be one of the most renowned military leaders by many historians and today he is widely considered a Czech national hero. He was born in the small village of Trocnov (now part of Borovany) in the Kingdom of Bohemia into an aristocratic family.

Early in 1423, internal dissent among the Hussites led to civil war. Zizka, as leader of the Taborites, defeated the men of Prague and the Utraquist nobles at Horice on April 20. Shortly afterwards came news that a new crusade against Bohemia was being prepared. This induced the Hussites to conclude an armistice at Konopiste on June 24. As soon as the crusaders had dispersed, internal dissent broke out anew. During his temporary rule over Bohemia, Prince Sigismund Korybut of Lithuania had appointed Borek, the lord of Miletinek, governor of the city of Hradec Kralove. Borek belonged to a moderate Hussite faction, the Utraquist party. After the departure of Sigismund Korybut, the city of Hradec Kralove refused to recognize Borek as its ruler, due to the democratic party gaining the upper hand. They called Zizka to its aid. He acceded to the demand and defeated the Utraquists under Borek at the farm of Strachov, near the city of Hradec Kralove on August 4, 1423. Zizka now attempted to invade Hungary, which was under the rule of his old enemy King Sigismund. Though this Hungarian campaign was unsuccessful owing to the great superiority of the Hungarians, it ranks among the greatest military exploits of Zizka, on account of the skill he displayed in retreat. In 1424, civil war having again broken out in Bohemia, Zizka decisively defeated the "Praguers" and Utraquist nobles at Skalice on January 6, and at Malesov on June 7. In September, he marched on Prague. On the 14th of that month, peace was concluded between the Hussite parties through the influence of John of Rokycany, afterwards Utraquist archbishop of Prague. It was agreed that the now reunited Hussites should attack Moravia, part of which was still held by Sigismund's partisans, and that Zizka should be the leader in this campaign. However, he died of the plague at Pribyslav on October 11, 1424 on the Moravian frontier. According to chronicler Piccolomini, Zizka's dying wish was to have his skin used to make drums so that he might continue to lead his troops even after death. Zizka was so well regarded that when he died, his soldiers called themselves the Orphans (sirotci) because they felt like they had lost their father. His enemies said that "The one whom no mortal hand could destroy was extinguished by the finger of God." He was succeeded by Prokop the Great.

Question: Francisco Pizarro was born in Trujillo, Caceres, Spain (then in the Crown of Castile) in modern-day Extremadura, Spain. He was the illegitimate son of infantry colonel Gonzalo Pizarro (1446-1522) and Francisca Gonzalez, a woman of poor means. His date of birth is uncertain, but it is believed to be sometime in the 1470s, probably 1474. Little attention was paid to his education and he grew up illiterate.

On 10 November 1509, Pizarro sailed from Spain to the New World with Alonso de Ojeda on an expedition to Uraba. He sailed to Cartagena and joined the fleet of Martin Fernandez de Enciso and, in 1513, accompanied Balboa to the Pacific. In 1514, he found a supporter in Pedro Arias Davila, the Governor of Castilla de Oro and was rewarded for his role in the arrest of Balboa with the positions of mayor and magistrate in Panama City, serving from 1519 to 1523. Reports of Peru's riches and Cortes's success in Mexico tantalized Pizarro. He undertook two expeditions to conquer the Incan Empire in 1524 and in 1526. Both failed as a result of native hostilities, bad weather and lack of provisions. Pedro de los Rios, the Governor of Panama, made an effort to recall Pizarro, but the conquistador resisted and remained in the south. In April 1528, he reached northern Peru and found the natives rich with precious metals. This discovery gave Pizarro the motivation to plan a third expedition to conquer the area. He returned to Panama to make arrangements, but the Governor refused to grant permission for the project. Pizarro returned to Spain to appeal directly to King Charles I. His plea was successful and he received not only a license for the proposed expedition, but also authority over any lands conquered during the venture. He was joined by family and friends and the expedition left Panama in 1530. When hostile natives along the coast threatened the expedition, Pizarro moved inland and founded the first Spanish settlement in Peru, San Miguel de Piura. Atahualpa refused to tolerate a Spanish presence in his lands, but was captured by Pizarro during the Battle of Cajamarca on 16 November 1532. A ransom for the emperor's release was demanded and Atahualpa filled a room with gold, but Pizarro charged him with various crimes and executed him on 26 July 1533, overriding his associates who thought he was overstepping his authority. The same year, Pizarro entered the Inca capital of Cuzco and completed his conquest of Peru. In January 1535, Pizarro founded the city of Lima, a project he considered his greatest achievement. Quarrels between Pizarro and his longtime comrade-in-arms Diego Almagro culminated in the Battle of Las Salinas. Almagro was captured and executed and, on 26 June 1541, his embittered son, Diego de Almagro "el mozo", assassinated Pizarro in Lima. The conquistador of Peru was laid to rest in the Lima Cathedral.
