A small, tiny, random little puzzle (ended)

Hello everyone,
I’ve prepared a tiny train for you. Honestly, I wanted to create a much more elaborate puzzle, but I guess I feel too tired to put that much mental energy into it. So instead, I’ve made a quite simple puzzle.

Also, I’m currently at a significant turning point in my life. In a few months, it will be decided which hospital and department I’ll start my residency in. Right now, I’m waiting for the available positions to be announced, and afterwards, I’ll make my preferences and start working once I get placed. (I was working before, but since I resigned from my previous residency, I’ve found myself going through this difficult process again.)
So if you can send me some good wishes—according to your beliefs—I would greatly appreciate it.

Now, here’s the puzzle: It’s the most well-known single-word name of a historical figure who can be considered the founder of my home country. I don’t want to dive into politics, but while many people in my country dislike this historical leader, for the world—and especially for me—he is a very important figure and an idol. I’m not asking for his full name, just the most commonly known one-word name he’s referred to by (just English characters).
