Today is the 500th anniversary of the battle of Mohács in 1526 when the Ottoman forces overwhelmed the Hungarian army led by King Louis II and broke the ability of the realm to defend itself. In the folk memory of Hungarians it remains an unparalleled disaster.
This was to be followed by the Ottoman occupation of central Hungary in 1541, capturing Buda exactly fifteen years later on August 29th 1541, leaving the Habsburg King Ferdinand I with the west and north of the kingdom and his rival King John I from the Zápolya family holding Transylvania, and the Holy Crown of St Stephen. The Holy Crown was eventually returned to King Ferdinand and the eastern kingdom recognised as the principality of Transylvania under Ottoman suzerainty. 161 years after the battle is 1526 a second battle, almost on the anniversary, saw the Habsburg forces smash the Ottoman army in the second battle of Mohács and free most of the historic Hungarian realm from Turkish rule.

Recent research into the abnormally wet weather conditions in 1526 in Hungary is set out in an article from Daily News Hungary.com at Was the weather completely different 500 years ago? This is what was recorded in the days before the Battle of Mohács
Wikipedia also has a biography of the unfortunate King Louis II who drowned in the flight from the battlefield aged only twenty. This can be seen at Louis II of Hungary
