首先，1L搬运，前面是CK2维基原文，后面中文自己翻译的，不知其他人之前发过没
Culture flipping
There are special events allowing some cultures to give rise to new ones, and allowing these new cultures to spread quickly within the old ones.
Norse splits into several cultures starting in 950. This is prevented if the top liege has Norse culture and hold either an empire or multiple kingdoms (it doesn't matter which ones) or if the province owner's head of religion is of Norse culture.
Norman is formed if a Norse ruler owns a French, Occitan or Breton province.
English is formed if a Norman ruler owns an Anglo-Saxon province after 1100.
Many cultures only appearing in the 769 Charlemagne start date:
Saxon flips to German once Widukind rebellion has happened, unless controlled by a powerful Saxon ruler or if head of religion is a Saxon
Visigothic splits up into Castillian, Catalan, Occitan, and Andalusian unless controlled by a powerful Visigoth ruler or if head of religion is Visigothic
Suebi (flips to Portuguese)
Frankish (flips to French, or Dutch if in de jure Frisia)
Pictish flips to Scottish unless controlled by a powerful Pictish ruler or if head of religion is Pictish
Lombard (flips to Italian)
Frisian (flips to Dutch)
Ilmenian, Severian, Volhynian (merge into Russian when ruler is one of:
1) a reformed pagan
2) not of East Slavic or Finno-Ugric culture
3) already Russian)
文化转化
特殊事件允许一些文化产生新文化，并允许这些新文化在旧文化中迅速传播。
从950年起，诺斯文化开始分化，除非其被一个拥有帝国或多个王国（不管是哪几个）的诺斯统治者控制，或其宗教领袖是诺斯人。
一个诺斯统治者拥有法兰西，奥克或布列塔尼文化的省份，会建立诺曼文化。
1100年后，一个诺曼统治者拥有盎格鲁-撒克逊文化的省份，会建立英格兰文化。
许多文化只出现在769年的查理曼剧本中：
威德金特叛乱爆发后，撒克逊文化转化为德意志文化，除非其被一个强大的撒克逊统治者控制，或其宗教领袖是撒克逊人。
西哥特文化分化为卡斯提尔，加泰罗尼亚，奥克和安达卢西亚文化，除非其被一个强大的西哥特统治者控制，或其宗教领袖是西哥特人。
苏维汇文化转化为葡萄牙文化。
弗里斯兰法理领土内的法兰克文化转化为荷兰文化，其他法兰克文化转化为法兰西文化。
皮克特文化转化为苏格兰文化，除非其被一个强大的皮克特统治者控制，或其宗教领袖是皮克特人。
伦巴第文化转化为意大利文化。
弗里斯兰文化转化为荷兰文化。
当其统治者达成其中一项时，Ilmenian，Severian和沃里尼亚文化融入罗斯文化：
1）改革原始宗教
2）不属于东斯拉夫或芬兰-乌戈尔文化
3）已经是罗斯人

我767沃里尼亚改革了原始斯拉夫能不能变罗斯啊
