History behind the term 'Brothers And Sisters'

14th century

Sibling Terminology

The term 'brother' and 'sister' can be traced back to the 14th century when they were used to refer to siblings. In Old English, 'brother' derived from the Proto-Germanic word 'brothar,' while 'sister' came from the Proto-Germanic word 'swester.' These terms were commonly used to describe the familial bond between individuals who shared at least one parent.

17th century

Religious Siblings

During the 17th century, the term 'brothers and sisters' began to gain significance in religious contexts. In Christianity, believers were often referred to as 'brothers and sisters in Christ,' emphasizing the spiritual kinship among followers of the faith. This terminology highlighted the idea of a united family, where believers shared a common bond through their shared religious beliefs.

19th century

Social and Political Brotherhood

In the 19th century, the term 'brothers and sisters' took on a broader social and political connotation. It became a powerful metaphor for equality, unity, and the collective struggle for justice. Activist movements, such as the suffragettes, emphasized the notion of 'brothers and sisters' to advocate for gender equality, recognizing that both men and women should stand together in the fight for women's rights.

20th century

Civil Rights Era

During the 20th century, 'brothers and sisters' gained significant traction within the Civil Rights Movement. Leaders like Martin Luther King Jr. frequently used the phrase to foster a sense of togetherness among individuals fighting against racial discrimination. By referring to fellow activists as 'brothers and sisters,' they aimed to foster solidarity and emphasize the shared goals and aspirations for a more inclusive society.


Universal Brotherhood
