The query "what happened in 19" is ambiguous as it could refer to a specific year starting with "19" (e.g., 1919, 2019) or the entire 19th century (1801-1900). Clarifying the focus:
- If it's about a specific year like 1919 or 2019, I can provide events from that year.
- If it's about the 19th century, I can summarize major historical events throughout the century.
Could you please specify if the interest is in a specific year or the whole 19th century?
