Tails was first released in [August 2009](https://lists.torproject.org/pipermail/tor-talk/2009-August/002667.html), when it was still called `amnesia`.In 2019, Tails [[celebrated 10 years of existence|news/celebrating_10_years]].
Tails could not exist without [[Debian|https://www.debian.org/]], [[Debian Live|https://www.debian.org/devel/debian-live/]], and [[Tor|https://www.torproject.org/]]; see our [[contribute/relationship with upstream]] document for details.

Tails was inspired by the [[Incognito LiveCD|https://web.archive.org/web/20090220133020/http://anonymityanywhere.com/]]. The Incognito author declared it to be dead on March 23rd, 2010, and wrote that Tails "should be considered as its spiritual successor".

The [[Privatix Live-System|http://mandalka.name/privatix/]] was an early source of inspiration, too.
