With President Obama turning to Congress for a decision on Syria, BuzzFeed offers a quick Hill history lesson. Congress hasn't formally declared war since 1942, the site notes. But before that, it wasn't such a rare move:
- Congress backed war against Britain in 1812, by way of a joint resolution that passed the Senate 19-13. The conflict was fueled by trade and other disagreements following the American Revolution.
- Congress declared war on Mexico in 1846 amid border conflicts; Mexico surrendered the following year, and the southwestern US expanded quite a bit.
- Capitol Hill declared war on Spain in 1898 following the explosion of the USS Maine, sent to protect US interests in a volatile Cuba.
- War with Germany was declared in 1917 after evidence emerged that Germany planned to help Mexico regain southwestern US territories.
- And in 1941, after Pearl Harbor, a unanimous Senate backed war with Japan, Germany, and Italy; the next year, it was Bulgaria, Hungary, and "Rumania."
