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.

1. the townshend acts of 1767 “threaten the country with poverty and ruin.”

at a town meeting held at faneuil hall in boston on october 28, 1767, boston freeholders and residents discussed the implications of the brutal townshend acts levied against the colonists. the townshend acts were a set of four acts passed by the british parliament in the summer of 1767 in order to generate revenue for the crown (through duties on goods such as lead, glass, paper, and tea) as well as exert british control over the increasingly rebellious colonists.

during the oct. 28 meeting, the bostonians found:

the excessive use of foreign superfluities is the chief cause of the present distressed state of this town, as it is thereby drained of its money: which misfortune is likely to be increased by means of the late additional burthens and impositions on the trade of the province, which threaten the country with poverty and ruin.

as a result, the citizens unanimously voted to boycott all british-made goods.
