Hey there, kiddo! So, Bessarabian Bulgarians are a group of people who live in a place called Bessarabia. Imagine Bessarabia as a big puzzle piece that fits in between two other puzzle pieces - Romania and Ukraine.
Now, Bessarabia used to be part of another country called Moldova before it became part of Romania in 1918. The people who lived there are a mix of different cultures, but some of them are Bulgarians.
Bulgarians are people who come from a country called Bulgaria, which is right next to Bessarabia. They have their own language, traditions, and way of life. When the Bulgarians moved to Bessarabia, they brought all of their customs and traditions with them.
So, Bessarabian Bulgarians are basically people who are Bulgarian but live in Bessarabia. They have a unique culture and way of life that has been shaped by the place they live in and the people around them. Does that make sense?
