Nope, was not under Venetian rule in 1212.
True, but those were just a couple of islands and a coastal town.
You mean the fort of Durazzo...
Not under direct Venetian rule, merely occupied after taken from the Genoans and soon given to the Despot of Epirus.
A tributary at best.
Lol, what dominance?
99% of Istria is still in the hands of ze Germans and in Dalmatia Venice has a couple islands and Zadar.
I get what you are trying to say, but if you look at the main province of Venice, you will realize that I am still technically right, as that province is larger than all those miniscule little enclaves of territory you just mentioned.
It is not just semantics because the Venice you know was created through the 14th/15th century and afterwards.
This mods startdate is merely a decade after the sack of Constantinople and, apart from their fleet and trade income, Venice was definitely not a "major power" regardless of the influence they had in the region.
They nearly always merely meddled into affairs and rarely ever had the direct power to mount their own wars, that is until a few decades after this mods start date when the profits from the fourth Crusade finally elevated it into, what you could describe as a "major power".
Heck, their first war for dominance in the region against Genoa did not even happen until 1256.
