Answer:
The Ivans were conquests. Ivan changed how the russian army was structured and was the first Tsar to start a well-formed army. He did this so he could do a stategic plan which then lead to a bunch of conquests, in other words, murder. Ivan had a great impact to Russia, he introduced to the army western military technology. It made him very well-known.
Ivan's life was harsh. Ivan became Ivan the Terrible because he was neglected, hungry, and abused as a kid. Both emotionally and most-likely physically. Therefore, he developed a lot of hatred over the years. However, at the age of 16 he was crowned as the Tsar of all of Russia. Despite Ivan's early life, he proved to be capable.
There is a lot of things Ivan the Terrible did for the Russian Empire. He rebuilt Moscow after a fire, introduced the first parliament, founded a standing army known as the "Steltzi", reformed the church, and even stamped out many clerical abuse cases. So this is the effect Ivan had on Russia.
(Sorry this took so long, I had to do a lot of research and form my own words, I know nothing about Russia lol)
