The oldest, most metal-poor stars in the Milky Way formed in pristine environments in the early Universe and preserve unique clues to the first generations of stars and to our Galaxy's early assembly. The oldest stars are expected in the Milky Way's inner regions, and metal-poor populations across our Galaxy and its satellites inform our broader understanding of early galaxy formation. I will discuss current views on the Milky Way's early history from two perspectives: metal-poor stars in the central Galaxy from the Pristine Inner Galaxy Survey (PIGS), and populations of carbon-enhanced metal-poor (CEMP) stars that carry the imprint of the first stars and binary interaction. I will highlight recent results and current open questions, and discuss the expected contributions of the upcoming WEAVE and 4MOST surveys.
