Problem: Background: Ashkenazi Jews, also known as Ashkenazic Jews or simply Ashkenazim (Hebrew: ash@k@'nazi'ym, Ashkenazi Hebrew pronunciation: [,aSk@'nazim], singular: [,aSk@'nazi], Modern Hebrew: [aSkena'zim, aSkena'zi]; also y@hv'dey ash@k@'naz Y'hudey Ashkenaz), are a Jewish diaspora population who coalesced as a distinct community in the Holy Roman Empire around the end of the first millennium. The traditional diaspora language of Ashkenazi Jews is Yiddish (a Germanic language which incorporates several dialects), with Hebrew used only as a sacred language until relatively recently. Throughout their time in Europe, Ashkenazim have made many important contributions to philosophy, scholarship, literature, art, music and science. Ashkenazim originate from the Jews who settled along the Rhine River, in Western Germany and in Northern France.
Context: The name Ashkenazi derives from the biblical figure of Ashkenaz, the first son of Gomer, son of Japhet, son of Noah, and a Japhetic patriarch in the Table of Nations (Genesis 10). The name of Gomer has often been linked to the ethnonym Cimmerians. Biblical Ashkenaz is usually derived from Assyrian Askuza (cuneiform Askuzai/Iskuzai), a people who expelled the Cimmerians from the Armenian area of the Upper Euphrates, whose name is usually associated with the name of the Scythians. The intrusive n in the Biblical name is likely due to a scribal error confusing a waw v with a nun n.  In Jeremiah 51:27, Ashkenaz figures as one of three kingdoms in the far north, the others being Minni and Ararat, perhaps corresponding to Urartu, called on by God to resist Babylon.  In the Yoma tractate of the Babylonian Talmud the name Gomer is rendered as Germania, which elsewhere in rabbinical literature was identified with Germanikia in northwestern Syria, but later became associated with Germania. Ashkenaz is linked to Scandza/Scanzia, viewed as the cradle of Germanic tribes, as early as a 6th-century gloss to the Historia Ecclesiastica of Eusebius. In the 10th-century History of Armenia of Yovhannes Drasxanakertc'i (1.15) Ashkenaz was associated with Armenia, as it was occasionally in Jewish usage, where its denotation extended at times to Adiabene, Khazaria, Crimea and areas to the east. His contemporary Saadia Gaon identified Ashkenaz with the Saquliba or Slavic territories, and such usage covered also the lands of tribes neighboring the Slavs, and Eastern and Central Europe. In modern times, Samuel Krauss identified the Biblical "Ashkenaz" with Khazaria.  Sometime in the early medieval period, the Jews of central and eastern Europe came to be called by this term. Conforming to the custom of designating areas of Jewish settlement with biblical names, Spain was denominated Sefarad (Obadiah 20), France was called Tsarefat (1 Kings 17:9), and Bohemia was called the Land of Canaan. By the high medieval period, Talmudic commentators like Rashi began to use Ashkenaz/Eretz Ashkenaz to designate Germany, earlier known as Loter, where, especially in the Rhineland communities of Speyer, Worms and Mainz, the most important Jewish communities arose. Rashi uses leshon Ashkenaz (Ashkenazi language) to describe German speech, and Byzantium and Syrian Jewish letters referred to the Crusaders as Ashkenazim. Given the close links between the Jewish communities of France and Germany following the Carolingian unification, the term Ashkenazi came to refer to both the Jews of medieval Germany and France.

Problem: Background: Alaska Natives are indigenous peoples of Alaska, United States: Inupiat, Yupik, Aleut, Eyak, Tlingit, Haida, Tsimshian, and a number of Northern Athabaskan cultures. They are often defined by their language groups. Many Alaska Natives are enrolled in federally recognized Alaska Native tribal entities, who in turn belong to 13 Alaska Native Regional Corporations, who administer land and financial claims. Ancestors of the Alaska Natives are known to have migrated into the area thousands of years ago, in at least two different waves.
Context: In 1971 the United States Congress passed the Alaska Native Claims Settlement Act (ANCSA), which settled land and financial claims for lands and resources which the peoples had lost to European Americans. It provided for the establishment of 13 Alaska Native Regional Corporations to administer those claims. Similar to the separately defined status of the Canadian Inuit and First Nations in Canada, which are recognized as distinct peoples, in the United States, Alaska Natives are in some respects treated separately by the government from other Native Americans in the United States. This is in part related to their interactions with the US government in a different historic period than indigenous peoples in the colonies and early federal period.  Europeans and Americans did not have sustained encounters with the Alaska Natives until the late nineteenth and early twentieth centuries, when many were attracted to the region in gold rushes. The Alaska Natives were not allotted individual title in severalty to land under the Dawes Act of 1887 but were instead treated under the Alaska Native Allotment Act of 1906.  It was repealed in 1971, following ANSCA, at which time reservations were ended. Another characteristic difference is that Alaska Native tribal governments do not have the power to collect taxes for business transacted on tribal land, per the United States Supreme Court decision in Alaska v. Native Village of Venetie Tribal Government (1998). Except for the Tsimshian, Alaska Natives no longer hold reservations but do control some lands. Under the Marine Mammal Protection Act of 1972, Alaska Natives are reserved the right to harvest whales and other marine mammals.
