Byzantines Plunder Pliska

An emperor seizes a khan's treasure

Byzantine Emperor Nikephoros I led his army deep into Bulgarian territory and captured the capital city of Pliska, seizing Khan Krum's royal treasury. The audacious raid seemed like a great triumph, but it was a fatal overreach. Within days, Krum would ambush and annihilate the Byzantine army in a mountain pass, killing Nikephoros and turning his skull into a drinking cup.

Canada Closes Its Doors

A young nation guards its borders

Pressed by expanding immigration and growing public anxiety, Canada enacted restrictions closing its doors to paupers and criminals. The policy reflected the tensions of a young nation grappling with rapid demographic change at the dawn of a new century, as waves of newcomers from Europe tested the limits of Canadian hospitality and forced difficult conversations about belonging.
