Why was it historically important?

I don't know if I'd say it was historically important but the match certainly had a lot of things going for it:

• Most obviously, it was a Grand Slam final. Grand Slams are undoubtedly the most important events on the tour, the ones the players are aiming for. It's arguably historical (in sporting terms) for anyone to win a Grand Slam, because it is more prestigious than a non-Grand Slam event.

• Federer is hugely popular, and considered by many to be the GOAT. However, he is 35 years old and before today he hadn't won a Grand Slam in almost five years. I think most had given up hope that he would get the 18th, but that gap between the 17th and 18th Grand Slam will make this all the more memorable.

• Not only did he win, but he did it against Nadal, his greatest rival. Seeing Federer and Nadal in a Grand Slam final together (which I think last happened in 2011) is downright nostalgic considering the history between both players. They are two giants of the sport, though due to a combination of age and injury I doubt many would have put money on them meeting in a Grand Slam final this year.
