Contemporary era history

From 1989 through 1991, Poland engaged in a democratic transition which put an end to the Polish People's Republic and led to the foundation of a democratic government, known as the Third Polish Republic, following the First and Second Polish Republic.
After ten years of democratic consolidation, Poland joined NATO in 1999 and the European Union on 1 May 2004.

The largest naval battle in history is a disputed title between adherents of varying criteria which include the numbers of personnel and/or vessels involved in the naval battle, the total displacement of the vessels involved and sometimes the significance and/or implications of the battle.
While battles fought in modern times are comparatively well-documented, the figures from those in pre-Renaissance era are generally believed by contemporary chroniclers to be exaggerated.
