If you're still fuming over taxes this year, take a look at Mike Duncan and Jason Novak's (slightly biased) cartoon explanation of the history of taxes. The income tax really got its start in 1913:
Congress immediately passes the Revenue Act of 1913, creating the first permanent income tax. No one really notices because the vast majority of incomes are taxed at just 1%. The mustache twirling robber barons get pretty grumpy, though. Then Wilson plunges us into WWI and unleashes the awesome potential of the new income tax. The top end rate jumps to 77% and revenue increases 635%.
