Love Parade (Duisburg, Germany, 2010)

The 2010 Love Parade in Duisburg, Germany, resulted in a catastrophic crowd crush that killed 21 people and injured over 650, marking the permanent end of the iconic techno festival. The disaster unfolded when a single, narrow tunnel, only 18 meters wide, served as the sole entrance and exit to the festival grounds, which were critically unsuitable for the estimated 1.4 million attendees. This bottleneck created extreme congestion and high crowd density, triggering a phenomenon described as "crowd turbulence" rather than a simple stampede, and proved significantly more fatal than the Roskilde Festival (Denmark, 2000) where nine people died.
