Step 1: Concept
In the Mughal Empire, it was common for princesses to adopt pen names or sobriquets that reflected their literary or scholarly pursuits. These pen names often indicated a particular virtue or quality.
Step 2: Meaning
The term 'pen name' refers to a pseudonym used by writers and artists to sign their work. In the context of Mughal Princesses, these pen names were not only for personal use but also reflected their intellectual contributions and values.
Step 3: Analysis
Makhli was one of the many pen names adopted by Zeb-un-Nisa, who was a renowned scholar and writer during the Mughal era. She was the daughter of Emperor Shah Jahan and Mumtaz Mahal. Zeb-un-Nisa wrote extensively on various subjects including philosophy, history, and literature under her pen name.
Gulbadan Begum, Jehanara, and Nurjahan were also notable figures in the Mughal court but did not use 'Makhli' as their pen name.
Gulbadan Begum was known for her historical work "Tuzk-e-Gulbadan."
Jehanara was a poet and writer who wrote under various names, but not specifically 'Makhli.'
Nurjahan was the wife of Emperor Jahangir and had several titles and pen names, none being 'Makhli.'
Step 4: Conclusion
Given that Zeb-un-Nisa is known to have used 'Makhli' as her pen name for her literary works, it can be concluded that she was the Mughal Princess who adopted this particular sobriquet.
