Sack of Braavos

The Sack of Braavos was a punative event during the late stage of the War of the Narrow Sea. Westerosi forces under Lady Sansa Stark, Lord Jaime Lannister and Lady Yara Greyjoy, successfully invaded and occupied the city of Braavos before looting and razing, among other places, the Iron Bank of Braavos. The sack significantly dimished Braavos' strength and prominence, and effectively ended the Iron Bank's existence as an institution.
