Meet the Ambanis, who live in a $1 billion skyscraper and are hosting another lavish wedding

The Ambanis are one of Asia's richest families.

The family patriarch, Mukesh Ambani, has an estimated net worth of $121 billion, making him the 11th-richest person in the world, according to Bloomberg. 

The Indian family's massive wealth began with Dhirubhai Ambani, who founded Reliance Industries to manufacture fabrics and textiles.

Dhirubhai died in 2002 at age 69 without a will, leaving his company to be run by his sons Mukesh and Anil.

A bitter succession battle between the two brothers followed their father's death and resulted in a rivalrous relationship between Mukesh and Anil.

Ultimately, Mukesh was left in charge of the majority of Reliance.

In 2005, the brothers agreed to split control, with Mukesh overseeing oil and gas operations.

Anil took over construction, telecommunications, asset management, entertainment and power generation businesses.

Anil Ambani is chairman of Reliance Group but has only a fraction of his older brother's wealth.

Bloomberg reported that 2018 saw Anil's businesses suffer from "legal and liquidity challenges."

Indian media reported in September 2018 that Anil's "cash-strapped" Reliance Communications will quit the telecom business and turn to real estate.

In early 2020, Anil told a UK court that his net worth was in fact "zero" and that he was bankrupt.

Mukesh Ambani is married to Nita Ambani.

Nita is the chair of Reliance Foundation, the company's charitable organization.

She's also involved with the company's sports ventures as well as marketing and branding strategy for Reliance Jio Infocomm, Reliance's mobile network operator.

Nita and Mukesh have three children, with the youngest Anant, 29

Then there are 32-year-old twins Isha and Akash Ambani.

Akash is a board member at Reliance Jio. Both he and his twin sister studied at Ivy League universities in the US, Akash at Brown University ...

Akash is married to his high school sweetheart, Shloka Mehta, the daughter of a well-known diamond merchant. Mehta reportedly studied at Princeton University and the London School of Economics.
