Kikin

History of Kikin
Princessdom of Kikin got their independent back in 1468 when, as Kikin clan, they repelled after the Ōnin war had started in Kyoto. Quickly gaining city under their rule, their allied themselves with the leader of other side of war, Hosokawa clan.

After war were over, Hosokawa decided to give Kyoto and half of Ashikaga shogunate's land to Kikin clan, in exchange of recognizing Hosokawa's overlordship, while allowing Shogun of Ashikaga to still reign in Kyoto.

In 1568, when Oda clan attacked Kyoto trying to unite Japan under their rule, Hosokawa quickly retreated from Kyoto, leaving Kikin clan alone defending Kyoto. Against all odds, Kikin won against Oda with their weak army.

The city itself was damaged hugely in siege, which also killed the ruler of clan without any male heir nor male relative. The clan would had most likely falled after that, if it wouldn't have been for daimyo's spouse, Chiyoko Maki (千代子 真木) who took the control of clan, and with her small reforms and diplomatic alliances, the clan was able to survive any other attacks of Oda clan or Hosokawa clan, who desired to get Kyoto back their control.

In 1613, under rule of Kazue Maki (和恵 真木), Kikin clan started to conquer other smaller clans around them. After conquering three smaller clans, Both Oda clan and Hosokawa clan joined in coalition against Kikin clan. Their unified army marched to Kyoto in 1615, facing only Kikin's army. The battle was easily won by the coalition, and Kazue was killed. Her husband, Naomi Kikin (直己 キキン) travelled with help of rest of army, to Uesugi clan's lands, who were one of their ally.

in 1628, after war had broken out between Oda and Hosokawa for control over Ashikaga Shogunate and Kyoto in 1625, Naomi led together with his allies an army to Kyoto, seizing control of Kyoto in middle of war, technically declaring the war to both of clans. Because of this, whole island of Japan get dragged into this threeway-war, which lasted until 1674. Little is known from this war, because of it's full-scale destruction of Japan, and thus, many clans were destroyed in the this over 50-years lasting full-scale civil war. From the clans of Hosokawa, Oda and Kikin, Hosokawa suffered least, while Oda clan was utterly destroyed. In the treaty of Yonezawa, it was agreed that, due to the amount of powerful clans dropped down to only 6 (Nanbu, Uesugi, Hosokawa, Kikin, Asakura and Ryūzōji), whole Japan was divided in 6 parts, with the clans getting all one.
