Peter 1st

Hello everyone! Now I want to tell about gobernor of Russia Peter 1st. So he is grand imperator of Russia. Due to him Russia began grand country. We pride of him!

This entry is mostly good, but there are some grammar and spelling problems.

I would correct it like this:

Hello everyone! Now, I want to talk about Emperor of Russia Peter I. He was a grand emperor of Russia. Because of him Russia became a great Country. We are proud of him!

We say "I want to talk about", not "I want to tell about."

Gobernor should be governor. But we would say "emperor" or "ruler".

"Due" is too formal. We would say "because of" here.

I hope that helps!
