History of Hungary
Modern Hungary had its beginnings in the eighth century AD, when the area was settled by the Magyars, nomadic tribes from central Volga. 
Their kingdom thrived and expanded. In the sixteenth century the Turks seized the central part of Hungary and the northern and western sections of the country accepted Austrian Hapsburg rule rather than submit to Turkish domination. In 1699 the Turks were driven out and the entire country came under Hapsburg rule. Continuing unrest and the defeat of Austria by the Prussians in 1866 culminated in the establishment of Austria-Hungary as a dual monarchy in 1867. The defeat of Austria-Hungary in 1918 was followed by the establishment of Hungarian nation, but with two-thirds of its former territory and almost 60 percent of its former population ceded to the surrounding states. In the Second World War Hungary sided with Germany against the Soviet Union and was finally occupied by Soviet forces as they pushed southward in 1945. In 1948 communists, with Soviet support, again seized control, beginning 42 years of Soviet domination. A popular anti-communist uprising in 1956 was brutally suppressed by the Soviet Union. As the Soviet Union began to collapse a new constitution in 1989 set the scene for Hungary's first multi-party elections in 1990 and initiated a free market economy. It joined NATO in 1999 and the EU in 2004.

"During 1073 AD, both King Solomon and his cousins were preparing for the coming struggle. The king sent his envoys to his brother-in-law, King Henry IV of Germany, while Geza and his brothers were seeking the help of their Polish and Czech relatives. In the beginning of 1074, before the Polish and Czech troops arrived, King Solomon led his armies against the dukes' territory and defeated Géza's troops on 26 February at Kemej. However, after the arrival of the reinforcement from Poland and Bohemia, the dukes' armies started a counter-attack and they won a decisive victory over King Solomon's troops on 14 March in the "Battle of Mogyoród". In the same year Prince Saint Laszlo and Prince Geza founded here a monastery in commemoration of the battle. The monastery was built on what we call today the "Hill of Stones" in hungarian "Kővár" .
