[Star Wars] where does the First Order's name come from?

What makes it "first"? Surely it is the 2789th Order in the galaxy's history. Is it someone's first attempt at something? Is it supposed to be revisionist, so that in a century, after the Jedi have been wiped out or something, people of a future order would look back on this one as the first ever? What's the evil reasoning behind calling it that?

No idea why the people in this comment section are giving such blatantly wrong answers when they clearly dont know. 

The real answer is from Aftermath:Empires End. The name comes from Rae Sloanes (the creator of the First Order) promise after the Battle of Jakku that they (The Empire) will start over on a fresh slate, “That is our first order. To begin again. And to get it right, this time”. 

At some point or another this promise got codified and became the groups name. Its the same way countries call them selves “Peoples Republics” to show their goal and what the purpose of the state is, though like in these real world scenarios, that promise did not stand the test of time.
