After the Battle of Lipany, the opposition to King Sigismund and the agreement with the Council was led by governor Jan Roháč of Dubá. However, after the Taborites lost several of their castles and were defeated on 19 August 1435 by Oldřich of Rožmberk in the Battle of Křeč, the moderate wing, led by Bedřich of Strážnice, took over the Táborite faction. Jan Roháč and his faithful fortified at his castle Zion, which was soon conquered and all the surviving defenders were hanged in the Old Town Square of Prague. On 25 January 1437, by mutual agreement with Sigismund, Tábor was promoted to royal city and received the town's coat of arms: an imperial eagle. On 8 February 1449, the remnants of the Taborite union were joined with the Catholic and Kališník nobility from southern Bohemia, and so the so-called Strakonice Unity was established, which was directed against the ever-growing power of George of Poděbrady. On 1 September 1452, the town of Tábor was suddenly occupied by the army of the land administrator Jiří of Poděbrady, and thus the independent political power of the Tábor union was ended.
