摘 要
在美国历史上，黑人的影响是巨大的。19世纪以前，在南方的奴隶制度还没有废除的时候，大量的黑人就通过辛勤的劳动为美国农业的发展做出很大的贡献。但是当时，北方的黑人在美国独立后即已获得自由。在美国立国后不久，他们就获得了选举权等政治权利。
南北战争结束后，美国黑人开始全面参政，很多地方都有了黑人的议员，从市长，州长，国会议员，到现在的两届国务卿，甚至于现今的当政总统。而大量解放了的黑人进入工厂，又为美国工业的发展做出了贡献。
在两次世界大战中，大量黑人参军，他们为了美国和世界的和平与自由，牺牲在战场上。黑人体力好，所以，在田径，篮球等体育运动上，为美国争取了很多荣誉。 赵琳个人资料
至于文化，黑人的影响也很大。蓝调，爵士乐，HIP POP等，都起源于黑人音乐。而黑人作家，好莱坞演员也很多。近几届的奥斯卡奖就很青睐黑人。
