Nursing has evolved significantly from its early roots in family and religious caregiving to a highly professional and globally coordinated field.

During the Ancient to Medieval periods (before 1600s), care was mainly provided by family members, temple attendants, and religious orders, often as acts of charity rather than as a profession. In the 1600s–1800s, monastic and charitable institutions offered organized care, though nursing remained low in social status compared to medicine.

A major turning point came with Florence Nightingale (1854–1860), whose work during the Crimean War and establishment of formal training schools helped shape modern nursing education and professional standards. By the late 1800s, hospital- based training schools emerged, defining nursing as a distinct, ethical, and skilled occupation.

The founding of the International Council of Nurses (ICN) in 1899 marked the start of global collaboration and advocacy for the profession. World Wars I and II further expanded nurses’ roles, visibility, and responsibilities.

By the mid-1900s, formal regulation, registration, and licensure became standard worldwide. The 1960s introduced advanced roles like nurse practitioners, while the late 20 th century saw nursing education move into universities and expand into specialties and leadership roles.

From the 1990s to 2000s, globalization increased nurse migration and raised ethical concerns about workforce distribution. The COVID-19 pandemic (2020) highlighted nurses’ vital role and the strain on global health systems. Recent reports (2023–2025) continue to emphasize workforce shortages, burnout, and the need for investment in education, leadership, and fair working conditions.
