一个英语句子的结构分析----高手帮忙

Then gradually between about AD 800 and 1150, English became less like German because those who ruled England spoken first Danish and later French.

1、分析前半句句子结构“Then gradually between about AD 800 and 1150, ”
2、我想知道because在此是连词还是介词？我总觉得是是介词，因为后面不是一个句子。有个定语从句我知道。反正是有点迷惑。高手帮忙解析一下

Answer 1

这句意思是，公元800到1150年之间，英语变得渐渐不像德语，因为这些控制英格兰的人是说丹麦语的，然后是说法语的
第一句就是一个短语不是句子，then gradually 放在后面这句来理解 AD公元的
because是连词 those ( )spoke first danish and later french 是一个完整的句子啊（who ruled england）是those 的定语从句
