Three reasons why george washington is president

- he was elected unanimously

- he participated in the Revolutionary war

- he helped the elaboration of the U.S. Constitution

Explanation:

George Washington became the U.S. president (1789-1797) because he was unanimously elected with 69 electoral votes. The main reasons for his election were his participation in the Revolutionary war (he was the Commander of the American forces) – he was considered a national hero,  and he also helped the elaboration of the U.S. Constitution in Philadelphia.  

He didn't have any public campaign, as he was considered very humble, which also influenced his election to be the first U.S. President.

union blockade

explanation:

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.
