Conquer Club

I have a question about winning a game by completing an objective in a freestyle game.
Say I was playing on Feudal War with 7 other players. I'm the last one to begin my turn and manage to conquer all six castles by the end of my turn. After I end my turn, do I win when any other player begins the next round, or do I have to press "Begin Turn" myself to achieve victory?

Also, would the case be different if I decided not to end my turn manually but let the timer run out of time (whether accidentally or deliberately) instead?

at the start of your turn, thus right after you have pressed your begin turn button.

therefor wether or not you actually ended your turn makes no difference

Would the same apply to team games. If say you had held the territories for completing an objective at the end of a round and you were the last one to end turn, does your team still win if your team member clicks "Begin Turn" (assuming that the opposing team hasn't captured the territories yet) or do you still need to press it yourself?

you need to hold the objectives yourself, you cannot share the objectives with your teammates and then assume you have won, you still need to be the one to press start turn yourself.

OK, thanks for clarifying on that.
