I would like you, Writeacher to help me check a few sentences. Thank you.

1) English Parliament was divided into two parties: the Whigs and the Tories. The former descended from the Parlamentarians.
2) They encouraged commercial and trade (?) progress and were supported by the middle class. The latter came from the Royalists. They were blund to the crown and were supported by the Church and the landowners.
3) During the reign of George I, who came from Germany, the ministers elected a Primed Minister, who had to take the king's place in the government of the country.
4) He managed to keep England out of European conflicts and to reduce taxes, including the import-export ones (??).
On the other hand, Walpole was accused of corruption and election cheating, which actually he did.

1) OK

2) They encouraged commercial progress and were supported by the middle class. The latter came from the Royalists. They were blund to the crown and were supported by the Church and the landowners.
"commercial" and "trade" are pretty much synonymous -- I don't know what "blund" means.

3) During the reign of George I, who came from Germany, the ministers elected a Primed Minister, who had to take the king's place in the government of the country. I don't understand the underlined part of this.

4) He managed to keep England out of European conflicts and to reduce taxes, including import-export taxes. On the other hand, Walpole was accused of corruption and election cheating, which he actually did.
