Why Is the Git Default Branch Shifting from master to main? Understanding the Debate

Recently many open‑source projects that you may have forked suddenly broke because their master branch was renamed to main, with the reason cited as concerns over racial insensitivity.

Movement Initiation

The rename campaign was started by well‑known tech blogger Scott Hanselman, who on June 8 urged developers to change their Git default branch from master to main. He argued that the term "Master‑Slave" used in some contexts carries inappropriate connotations and that a neutral term like "main" is clearer.

Scott also provided detailed instructions for renaming the default branch.

Many developers quickly voiced support. Chrome developer Una Kravets said that main is simpler, easier to remember, and that using it could make Black colleagues feel more comfortable.

She even mentioned the change on Twitter, tagging GitHub’s CEO. GitHub CEO Nat Friedman replied on Twitter that it’s a good idea and that they are already working on it.

This raises the question: does this mean all large open‑source repositories will have to rename master to main?

Opposing Voices

Some developers argue that while changing a single word may seem harmless, it can cause significant disruption for long‑standing projects, especially those with many downstream forks. The effort required to update documentation, scripts, and tutorials can be substantial.

One user, imbaniac, pointed out that the Git master branch has no relation to the "Master/Slave" metaphor and asked whether the cost of updating existing projects has been considered.

Git’s master has nothing to do with Master/Slave terminology; we have never seen a "Slave" branch.

What about the cost of updating existing projects, books, and tutorials?

imbaniac also joked that at least they didn’t lose a "Master" degree, hinting at the absurdity of the debate.

Who Named the Original Master Branch?

The original master branch name dates back to Git’s creator, Linus Torvalds. A recent comment from Linus about an Intel CPU vulnerability sparked curiosity about his stance on the naming controversy.
