the union blockade in the american civil war was a naval strategy by the united states to prevent the confederacy from trading.
the blockade was proclaimed by president abraham lincoln in april 1861, and required the monitoring of 3,500 miles (5,600 km) of atlantic and gulf coastline, including 12 major ports, notably new orleans and mobile. those blockade runners fast enough to evade the union navy could only carry a small fraction of the supplies needed. they were operated largely by british citizens, making use of neutral ports such as havana, nassau and bermuda. the union commissioned around 500 ships, which destroyed or captured about 1,500 blockade runners over the course of the war.
the crusades are one of the most significant events in the history of europe and the middle east. they were a series of religious wars carried out by christian crusaders from europe during the timeframe of the middle ages. beginning in 1095 ce, the crusades saw european knights and noblemen travel to the middle east in an attempt to capture the holy land away from muslim people that had controlled the region for the previous centuries. the term crusade means ‘cross’. therefore, the europeans that became crusaders viewed themselves as ‘taking up the cross’. in fact, many of the crusaders wore crosses on their clothing and armor as they made their pilgrimage to the holy land.
