Racism is not merely a societal issue—it is a deeply ingrained problem that impacts every facet of life. From economic inequality to healthcare disparities, the tentacles of systemic racism have shaped the trajectories of societies for countless generations. Gaining a clear understanding of its present manifestations and repercussions is vital in the quest for equality.

To provide this understanding, we have constructed an extensive timeline spanning 400 years, which underscores crucial moments that have influenced racial inequality, particularly within the realm of Science, Technology, Engineering, Mathematics, and Medicine (STEMM).

This timeline offers a compelling viewpoint on how systemic racism has grown, adapted, and persisted throughout history, profoundly affecting the representation and experiences of racial minorities in STEM fields. By comprehending these significant events and their cascading effects, you will acquire a deeper insight into the contemporary challenges faced by racially minoritized individuals in STEMM. Further, it will illuminate the necessary actions we must collectively undertake to build a more equitable future in STEMM education and professions.
