Explanation: US President Calvin Coolidge's administration covered most of the 1920s. He's an often forgotten president. This is in large part due to, despite being a progressive when governor, he largely refrained from major initiatives when president. He was a lawyer by profession, and believed in an interpretation of Federalism that we in the US would probably consider archaic today - that the Federal government's legal authority was limited, except insofar as it was necessary to mediate between parties or enable democracy. The states, then, would take care of things like increasing minimum wage, worker protections, etc.
... it... works like that in some states. That's kind of the issue.
That aside, he was renowned at the time for his taciturn wit - "Silent Cal" had a somewhat introverted nature.
As president, one of the few causes he did believe the Federal government had a duty to protect was the rights of minorities, however, and he took very strong positions on the issue in his speeches. His administration saw a (sadly failed) attempt to implement a Federal anti-lynching law to protect Black folk in racist-majority areas, he was a noted supporter of African-American-led educational and economic institutions, he opposed anti-Asian racism in a time of increasing "Yellow Peril" sentiment, and he signed an act that gave citizenship to all Native Americans in US territory in 1924 (... yes... it took that long).
For this minority-friendly position, Coolidge was adopted into the Lakota Nation in 1927, and given the name "Wanblí Tokáhe" - "Leading Eagle". While Coolidge's positions still left much to be desired by modern standards, especially considering that he still took a very assimilationist position as to the eventual fate of Native cultures, the fact is that he listened to Native activists of the period to an unprecedented degree, inviting them to the White House to share their concerns, adopting many of their proposals, and expressed an understanding of the diversity of Native peoples, not just as a homogenous mass to be 'othered', but as distinct groups filled with not only individual cultures, but factions and individuals who needed to be dealt with on the same terms of concern-and-negotiation as all other members of the civic body.
