(Won) its war for independence in 1783, the United state then struggled to establish its own economic and finanacial system.

Why "won" is wrong?

真老九

如果用won，必须有连词连接前后两个句子；所以只能用动名词，

Taurus

逗号前面是状语结构, 需要动词ing结构.

如果非要用won, 则从句中既缺连接词, 又缺从句主语. 正确的说法为:

After it won its war for independence in 1783, the United state then struggled to establish its own economic and finanacial system.

即使这样补充也有一定的问题, 注意这里的主句里还有一个then, 和after在意义上有一定的重复性, 都有"之后"的意思.

总之, 改为winning 最简单可靠.
