Who Promoted the ideals of equality and brotherhood above all others?

The ideals of equality and brotherhood were prominently promoted by Enlightenment thinkers such as Jean-Jacques Rousseau and Voltaire, who emphasized individual rights and social justice. Additionally, revolutionary movements, particularly during the French Revolution, championed these ideals as foundational principles, advocating for the rights of all citizens. Organizations and leaders, like the abolitionists in the 19th century, further advanced these concepts by fighting against slavery and advocating for civil rights.
