Beginner start

Updated Start

Play Petty King Murchad of Munster in 1066, get an heir, and read the Ireland decision before you create extra titles.

Who to play on the first night

This diagram shows a beginner Crusader Kings 3 loop from Murchad in 1066 through an heir and the Ireland decision.
Original Guide Annex diagram dated 2026-10-30.

Start the 1066 bookmark and choose Petty King Murchad of Munster. The bookmarks page recommends him for new players. The game also uses him for the in-game tutorial. You get a teacher and a recommended seat in the same character.

The classic goal from Munster is the Kingdom of Ireland. That is the decision to open when you want to know what the campaign is asking for. Read the tooltip on the decision. It lists the requirements that apply in your version.

Both lines live on the tooltip so they can change. If a video quotes an older number, the tooltip wins.

The historical page for this seat is Murchad of Munster.

Petty King Murchad of Munster in 1066 is recommended for new players and is the tutorial character. Forming the Kingdom of Ireland is the classic goal.

The 867 and 1066 bookmarks are the two starts that shipped with the base game. Murchad sits in the later of those two.

Get an heir before you get ambitious

This diagram starts a first night on pause, checks the heir, arranges a marriage when the line is empty, and keeps the launch rule in view.
Original Guide Annex diagram dated 2026-10-30, not a screenshot.

Pause as soon as the map appears. Open the character screen and look at the heir. The 1 Sep 2020 launch note is plain about the stakes. If you do not produce a suitable heir, the line ends and the game ends.

If the heir line is empty, arrange a marriage. A spouse is the ordinary way a ruler gets a child. Traits, claims, and alliances change from game to game, and the marriage window shows the person you are actually choosing.

Once a child exists, look again after a few years. Children can die. A second son or a daughter can matter under your succession law even when you already have one heir. The succession page explains why a spare is not always a quiet vassal.

Paradox's launch note says that if you do not produce a suitable heir, the line and the game end.

Official (Paradox press release, 1 Sep 2020)

Confederate Partition can hand a same-rank title to a child who then leaves independent, so the spare heir is a succession question and a family question at the same time.

The first clicks that are worth making

This diagram assigns the realm priest to convert a county, the spymaster to find secrets, and a look at realm laws before a new title.
Original Guide Annex diagram dated 2026-10-30, not a screenshot.

Open the council. The realm priest converts a county from that screen. Put the priest on conversion if a county in your realm follows a different faith and you want it changed. Leave the task running. Check the county later.

The spymaster has a find-secrets task. Set it if you want secrets you can turn into hooks. The other councillors can sit on a job you understand. You can move them when a war or a building needs them. Nothing on this page asks you to fill every seat on minute one.

Open the realm law screen before you create a title. Confederate Partition can create a title of your highest rank that you qualify for and have not created, then give it to a child. If you hold only one title of that rank, ordinary partition keeps the younger children as vassals. Create a second title of that rank when you mean to, after you have read the law.

Stress is on the character screen. Glance at it when a choice warns you.

Holding only one title of your highest rank keeps younger children as vassals under ordinary partition. The realm law screen shows what you can pass.

The launch note lists customizable rules among the 1 Sep 2020 features.

A calm first evening

Unpause in short stretches. Marry if you need to. Set the priest and the spymaster. Read the Ireland decision and do one requirement the tooltip actually lists. Save the war for a cause you can name.

When you do fight, open the declare-war screen and pick a casus belli. Claims, de jure wars, and holy wars are the sorts of causes that screen can offer. Mercenaries exist, because the launch note includes them, and the mercenary list shows the price if you hire any.

Stop for the night once you have an heir, a council task running, and a clear look at your top title. The first century page picks up from there and walks through the heirs who come after Murchad. Hybrid culture can wait. It needs Royal Court or Khans of the Steppe, and it needs acceptance.

Mercenaries are part of the 1 Sep 2020 feature line, alongside northmen raiders and peasant revolts.

Official (Paradox press release, 1 Sep 2020)

Hybrid cultures require the Royal Court DLC or the Khans of the Steppe DLC. The base cultural acceptance threshold is 40%.
