Kingdom points are the total number of points from all players who take part in the Kingdoms Battle. By completing tasks and scoring points, each Jarl contributes to the victory.

The Kingdoms Battle has special rules regarding points scoring. Points will be scored for the following actions:

• Destroying warriors from the enemy Kingdom (both in the enemy Kingdom and your home one)
• Plundering resource locations in the enemy Kingdom
• Attacking Invaders, Uber Invaders, and Ghosts in the enemy Kingdom

Note the conditions for earning points:

• If you join a Clan after the Competition was announced in the Events window, points for personal and clan achievements will not be awarded, even if you complete all the necessary tasks.
• If you leave the Clan before the Competition is over, your personal achievements are canceled.
• If you are not a Clan member when the Kingdom Battle commences, you will only be able to earn points for your Kingdom. Points for personal and clan achievements will not be awarded.
• If you move to another Kingdom after the Competition was announced, using the Drakkar or Novice's Relocation items, you will no longer be counted as a participant, all your personal achievements will be removed, and other Jarls will not earn points for attacking your Town.

Hence, you have to be a Clan member when the Kingdoms Battle appears in the "Soon to be active" block in order to earn points for your personal and clan achievements.
