This two-part series looks at the role played by the three monarchs, and their relationships with each other, in the outbreak of war, arguing that it is far greater than historians have traditionally believed.

Royal Cousins at War - Cousin marriage - Netflix

Cousin marriage is marriage between cousins (i.e. people with common grandparents or people who share other fairly recent ancestors). Opinions and practice vary widely across the world. In some cultures and communities, cousin marriage is considered ideal and actively encouraged; in others, it is subject to social stigma. In some countries, this practice is common; in others it is uncommon but still legal. In others, it is seen as incestuous and is legally prohibited: it is banned in China and Taiwan, North Korea, South Korea, the Philippines and 24 of the 50 United States. Supporters of cousin marriage where it is banned may view the prohibition as discrimination, while opponents may appeal to moral or other arguments. Worldwide, more than 10% of marriages are between first or second cousins. In the past, cousin marriage was practised within indigenous cultures in Australia, North America, South America, and Polynesia. Various religions have ranged from prohibiting sixth cousins or closer from marrying, to freely allowing first-cousin marriage. Cousin marriage is an important topic in anthropology and alliance theory. Children of first-cousin marriages may have an increased risk of genetic disorders, particularly if their parents both carry a harmful recessive mutation, but this can only be estimated empirically, and those estimates are likely to be specific to particular populations in specific environments. Children of more distantly related cousins have less risk of genetic disorders. In fact, a study of Icelandic records indicated that marriages between third or fourth cousins (people with common great-great- or great-great-great-grandparents) may produce the most children and grandchildren.

The Netherlands has also had a recent debate that has reached the level of the Prime Minister proposing a cousin marriage ban. The proposed policy is explicitly aimed at preventing “import marriages” from certain nations like Morocco with a high rate of cousin marriage. Critics argue that such a ban would contradict Section 8 of the European Convention on Human Rights, is not based on science, and would affect more than immigrants. While some proponents argue such marriages were banned until 1970, according to Frans van Poppel of the Netherlands Interdisciplinary Demographic Institute, they are confusing cousin marriage with uncle-niece marriage.
