As it is, our borders are very secured everywhere - except in the north. In the east we have Timurid Empire, our loyal ally and trusted friend, in the west we have Austria and the relations to them are excellent. No troubles are excepted of them, in the south we have Ethiopia and Swahili, both rather weak and the other is allied to us, no problems then. But int he north we have the Russian Alliance and Polish-Lithuania, both very strong economically and militarily, we can only hope they aren't interested of us for some time.
As you can see the Russian armies near our borders aren't the smallest possible, more likely the opposite. There's more of them, one stack in every province which shares border with us. They don't have these stacks on other borders. Either they are very scared of us or they are planning on something...
But now we need to start improving our influence in the east. We decided to guarantee the independence of every single state in India, we hope this'll get us involved in a profitable war.
Suddenly, something unexpected happened. Polish-Lithuania, together with Denmark and Mazovia, declares war on Muscowy. We ponder the situation for some time and decide it's for our best interests to get involved. We move our troops toward their borders and lay claim on Azow, one of their more profitable provinces in Crimea.
We declare war. The begin goes well, and there's not really any Russian armies in the south as they are fighting in Lithuania. They do however have rather large armies in Siberia which take over our holdings in Kazan, but which are soon pushed westwards by the fast advancing Timurid Army. We take over the Kazan holdings of Tver, Muscowy's trusted ally. They offer us peace willing to give up their prosperous gold mines. We accept this.
Meanwhile some rogue troops of Muscowy have invaded 3/5s of Golden Horde's territories. We send our trusted cavalry to drive them away. This is done easily with the Timurids advancing through the same steppes with their massive armies.
Meanwhile, Ming is on again and declares war on Bihari alliance. We decline their offer to join the war, if we hadn't been in a war already we might have even accepted it. In the end the war ends to white peace which is good for us.
The war on Russians is going better than excepted. We are at the gates of Moscow and the Mongols have take over Siberia. Polish-Lithuania makes a white peace which means we will be getting more Russians to fight. Not so good so we decide to try a peace.
Surprisingly they accepted. It gave Muscowy's Crimean holdings for us and Mordvar, formerly owned by Golden Horde, for the Timurid Empire. The north seems more secured - for now.
Right after the peace our military masterminds introduce gunpowder weapons for our armies, which we however won't be using yet on larger scale.
Meanwhile our allies in Bulgaria end up in a union under the Habsburg Austria, we can only hope this won't give them any more power over the Balkans.
Thanks to our expansions lately, we have became one of the wealthiest nations in the world. This is good, but we fear it might also bring mote enemies as well as friends. People have started to be interested of the east, the French sailed the Red Sea lately and we hope they are here with peaceful minds.
