This country did something for the very first time during these Olympics.
Round 88 -- 2012 London Olympics -- Xyvol
This was a landmark event that diversified the Olympics. The question asks for the country, not the event.
The country sent a certain type of person to the Olympics for the first time in that country's history.
There are actually two other countries who also did this.

Sent female athletes to the Olympics for the first time. Along with Saudi Arabia and Brunei, but no one cares about them apparently.
I actually found this one a couple of days ago, but got busy at work and didn't post. I figured it'd be found by now.
Hmm, how about historic architecture next?
