请教：英王加冕典礼誓词中的一句话

The King places his hand on the Bible, and the Archbishop administers the Oath

“Will you solemnly promise and swear to govern the Peoples of the United Kingdom of Great Britain and Northern Ireland, your other Realms and the Territories to any of them belonging or pertaining, according to their respective laws and customs?”

The King replies

“I solemnly promise so to do.”

 

your other Realms and the Territories to any of them belonging or pertaining 这句话我不太明白。

them 指什么？是指 Realms 吗？

这句话是不是可以写成：your other Realms and the Territories which belong or pertain to any of the Realms
