Ganga sent a contingent of Rathore troops under the command of his son Prince Maldeo, which fought in the historic Battle of Khanwa against the Mughal invader Babur.

[2] Ganga rose to the throne on 8 November 1515 as his older brother Rao Viramde was considered unfit to rule and was unable to gain the support of the Rathore nobility.

During his reign, the Sisodia king Rana Sanga (r. 1508–1528) embarked on a period of territorial expansion of Mewar after defeating various Sultanates in pitched battles, including the Lodhis.

[7] On various occasions, Ganga sent contingents of Rathore soldiers in aid of his brother-in-law's military campaigns and himself in person assisted him against Muzaffar Shah of Gujarat in reinstating Raimal on the throne of Idar.

Later writers assert that Ganga's fall was an accidental one due to opium, without giving any conclusive evidence to exonerate Maldeo from charge of patricide.
