Cognatic kinship is a mode of descent calculated from an ancestor counted through any combination of male and female links, or a system of bilateral kinship where relations are traced through both a father and mother.[1] Such relatives may be known as cognates.

The House of York was a cadet branch of the English royal House of Plantagenet. It fought with the House of Lancaster, another cadet branch of the House of Plantagenet, for the English crown in the second half of the 15th century. The differences ultimately led to the Wars of the Roses. These wars are so named because each house had a rose in its coat of arms: York a white one and Lancaster a red one. Three members of the House of York became kings of England in the late 15th century: Edward IV, Edward V and Richard III. The House of York descended in the male line from Edmund of Langley, 1st Duke of York, the fourth surviving son of Edward III. In time, it also represented Edward III's senior line, when an heir of York married the heiress-descendant of Lionel, Duke of Clarence, Edward III's second surviving son. It is based on these descents that the House of York claimed the English crown. Compared with its rival, the House of Lancaster, it had a superior claim to the throne of England according to cognatic primogeniture, but an inferior claim according to agnatic primogeniture. The reign of this dynasty ended with the death of Richard III of England at the Battle of Bosworth Field in 1485. It became extinct in the male line with the death of Edward Plantagenet, 17th Earl of Warwick, in 1499.
Succession to the Spanish throne follows male-preference cognatic primogeniture. A dynast who marries against the express prohibition of the monarch and the Cortes Generales, the legislative chamber of Spain, is excluded from the succession. Upon proclamation by the Cortes Generales, the monarch is to take an oath to discharge his duties faithfully, to abide by the Constitution and the law and ensure they are abided by, and to respect the rights of the citizens and of the Autonomous Communities.
The Altaic languages ( , al-TAY-ik) or Altaic sprachbund are a sprachbund comprising the Turkic, Mongolic and Tungusic language families. The grouping was previously proposed as a language family, a theory which found support in the 20th century but is now rejected by many linguists, who have concluded the similarities among Turkic, Mongolic, and Tungusic languages are better explained by areal convergence rather than a shared genetic lineage. There is still, however, a significant faction of academics advocating for the language label, as the debate is still running. These languages share agglutinative morphology, head-final word order, and some vocabulary. The once-popular theory attributing these similarities to a common ancestry has been questioned by most comparative linguists in favor of language contact, although it continues to be supported by a smaller, yet stable scholarly minority. Like the Uralic language family, which is named after the Ural Mountains, the group is named after the Altai mountain range in the center of Asia. The core grouping of Turkic, Mongolic, and Tungusic languages is sometimes referred to as "Micro-Altaic" or "Core-Altaic," while an expanded grouping that includes Koreanic and Japonic is labeled "Macro-Altaic". A group of scholars divided the Macro-Altaic family into two related branches: Altaic family (Turkic, Mongolic, and Tungusic) and Japano-Koreanic family (Japonic and Koreanic) which together are referred to as Transeurasian language family. Today, "Macro-Altaic", together with the idea that Japonic, Koreanic, or Ainu may be part of a genetically coherent family, has been firmly rejected, even by proponents of the Altaic theory. Consequently, the term "Altaic", (whether referred to as a language group or a sprachbund), now encompasses only the Turkic, Mongolic, and Tungusic languages. The Altaic family was first proposed in the 18th century. It was widely accepted until the 1960s and is still listed in many encyclopedias and handbooks, and references to Altaic as a language family continue to percolate to modern sources through these older sources. Since the 1950s, most comparative linguists have rejected the proposal, after supposed cognates were found not to be valid, hypothesized sound shifts were not found, and Turkic and Mongolic languages were found to have been converging rather than diverging over the centuries. The relationship between the Altaic languages is now generally accepted to be the result of a sprachbund rather than common ancestry, with the languages showing influence from prolonged contact. Altaic has maintained a limited degree of scholarly support, in contrast to some other early macrofamily proposals. Continued research on Altaic is still being undertaken by a core group of academic linguists, but their research has not found wider support. In particular it has support from the Institute of Linguistics of the Russian Academy of Sciences and remains influential as a substratum of Turanism, where a hypothetical common linguistic ancestor has been used in part as a basis for a multiethnic nationalist movement.
Before the 1921 destruction of Tulsa’s Greenwood District, Black residents had created a remarkable center of business and community life. The district included stores, professional offices, entertainment venues and homes owned by Black citizens. Understanding Greenwood means learning what was built—not only what was burned.
