Final answer:
Between the late 1790s and early 1800s, egalitarianism thrived, leading to increased liberalism, social reforms, and eventually universal male suffrage. Women in particular fought for and achieved suffrage by 1920 after a long struggle for equal rights. However, the progress made still did not fully extend to non-White people or all women until much later.
Step-by-step explanation:
From the late 1790s to the early 1800s, egalitarian ideals took root in several societies, leading to significant shifts toward equality. In the United States, the Declaration of Independence set forth the principle of "All men are created equal," inspiring a revolution that would challenge the status quo regarding the rights of women, and Black and Native American people. However, despite this revolutionary aim, the reality for these groups fell short of true equality. The late 18th and early 19th centuries saw the growth of liberalism and the spread of liberal legal codes across Europe, culminating in universal male suffrage after World War I. Women, energized by early feminist thought and the egalitarian claims of the French Revolution, fought relentlessly for suffrage, which was achieved in 1920 in the United States. Meanwhile, social reforms like improved public health, free elementary education, and changes to property and employment laws were realized, reflecting incremental steps toward a more egalitarian society.
