Write a question about the following article: Economic crisis occurred after the Swedish war of liberation because of the trade monopoly the king had granted the Hanseatic Lübeck in exchange for their support in recapturing the capital during the war. The discontent was used by two Catholic priests, former Bishop Peder Jakobsson of Västerås, a follower of Sten Sture the Younger, and Knut Mickelsson, who opposed the inclinations of Lutheranism which the king had displayed as early as 1524, who stirred up the emotions against the king and for the Sture family in the province.In the spring of 1525, the Dalecarlians held a meeting and wrote a letter in which they complained of the foreign bailiffs and the imprisonment of Sten Sture's widow Christina Gyllenstierna, and stated that they would renounce their fealty unless their demands were met. They reportedly contacted Søren Norby, who offered Christina marriage. The king managed to subdue the discontent by promising to meet their demands in May 1525, and the leaders fled to Norway. They were extradited in 1526, and executed through Breaking wheel in February 1527.
How many years after the Dalecarlians held a meeting were the leaders executed?
