Ultimania Omega for Final Fantasy X Timeline says so.

Around 3000 years ago

- Vast improvements were made in the magic civilization.
- Machina was invented.
- The use of machina became common through the whole of Spira.
- Machina technology reached its peak.

Around 1000 years ago

- War broke out between Zanarkand and Bevelle, this is later known as The Machina War.
Sorry for not linking to the source but the Cid's knights here might object to links to other forums. Google for it and you will see that it is on at least 3 other forums.

PS: I have the book also, so eventually I'll scan the timeline in... But it is in Japanese.
