The failure of Lehman Brothers in 2008 was the largest bankruptcy in US history. A number of factors contributed to its failure, including excessive risk taking on housing assets, high leverage, and unethical actions. When housing markets declined, Lehman's vulnerable financial position was exposed and it collapsed, with global economic effects. The replacement of the Glass-Steagall Act allowed greater risk taking and conflicts of interest, which also contributed to Lehman's downfall.
