Republican campaign?

[al Roumi]

I would suggest either a spy rush...

You don't get any political agents when going republican - don't fully understand why but it adds further to the difficulty. You can build the political buildings (secret societies in this case) but no agents...

Other possibility would be to switch to the navy and wreak havoc along the shores.

That's probably the way to go. I launched my realm divide without drydocks or even frigates, let alone a Warrior/Ocean.

OT Pardon my klatchian? Pure WIN.

Thanks!

What's a republican campaign? Like domination?

Nope, it's the choice you get when you get to realm divide -either support the shogun/emperor or break with the past and go a-historic with a republic of Japan. Presumably with your Daimyo as not-so-elected president or just a straight people's dictator.
