Git: How to Create a Branch from an Older Commit | Step-by-Step Tutorial + MCQs
📌 Learn how to create a Git branch from an older commit without affecting your existing branch! In this hands-on Git tutorial, you'll discover how to start a new line of development from any commit in your repository's history using the git branch command.
Many beginners assume that new branches can only be created from the latest commit (HEAD), but Git allows you to branch from any commit, making it easy to fix bugs in older versions, experiment with features, or maintain multiple release lines.
In this lesson, you'll build a Git repository from scratch, create multiple commits, create a new branch from an earlier commit, switch to that branch, and observe how the Working Directory, Staging Area (Index), and commit history change. You'll also learn how Git stores commit history and how multiple branches can share a common history before diverging.
🎯 In this lesson, you'll learn:
✅ How to create a branch from an older commit using git branch branch-name commit-id
✅ How to switch to the newly created branch using git switch
✅ Why creating a branch does not modify the existing branch
✅ How Git restores the Working Directory and Staging Area when switching branches
✅ How new commits create an independent line of development
✅ How to visualize branch divergence using git log --oneline --all
✅ How Git branches are simply movable pointers to commits
✅ The relationship between commits, branches, and snapshots in Git
