I was the duke of Navarra, vassal to the Umayyad empire. I managed to also get parts of Brittany and was conquering the vikings there one by one. Also, I had one county in southern France.
Then I had one last so, then became incapable and then died, leaving a one-year old child in control, due to Ultimogeniture inheritance.
Then France declared holy war for Navarra. The Umayyad empress decided to not defend it and I could not defend myself from France alone.
Then one of the french dukes claim war on the county in france. The empress decided to fight the war only with half her troops, and even though I tried to help, we were losing. In the middle of this, Lotharingia declared holy war on south-east spain, and the empress just stopped caring about defending me.
Then there was a war on Tyrany against the empress declared. I decided to join, since it appeared we would win.
During this war, I became adult.
Then France declared holy war for one of my provinces in Brittany, and Britain for another one.
France won it's war.
We got to 100% warscore on the Tyranny war, but the rebel leader refused to enforced demands until the British got my province.
And now, I have no army and the british come again with a holy war for my last county.
I was a catholic the whole time and lost all my lands to catholic holy wars.
