I believe Tiber Septim was a Nord, for the following reasons.

1. His bravery. Nords are well known for their bravery and courageous in battle. This sense also comes from Tiber, as his conquest of Tamriel as a whole is very daring and it would be more Nord-like behaviour, rather than Breton.

2. Speech. Nords are also known for having a slightly better way with words compared to most of the other current races inhabiting Tamriel. Tiber demonstrated this talent when his conquest reaches Valenwood. Knowing he would never be able to truly conquer Valenwood's untameable nature, he made a deal with the Bosmer and convinced their leader to swear fealty to him, although they would be allowed to stay an independent province.

3. Weaponry and armour. Tiber is often depicted holding a one-handed sword, as well as what appears to be heavy armour. Both these things are Nordic traits, especially the heavy armour when compared to a Breton.

For these reasons I strongly believe Tiber Septim was a Nord. Though, this does not rule out that he could have been an Imperial as Nords and Imperials share many traits. I'm a little on the fence with this one, as to whether he was Nord or Imperial. If there's someone who can confirm he's not Imperial or have strong evidence he's not, that would pretty much solidify him being a Nord.
