Through generations of idle servitude they had grown to specialize only in style. A bogus, extinguishable glamour: in 1947, with Independence, they had lost their state, and Mrs. Gandhi in 1971 had, without much public outcry, abolished their privy purses and titles."

Through 1971, the two sides tried and failed to find a settlement. The princes were willing to forgo their privy purses, but hoped at least to save their titles. But with her overwhelming majority in Parliament, the prime minister had no need to compromise. On 2 December she introduced a bill to amend the constitution and abolish all princely privileges. It was passed in the Lok Sabha by 381 votes to six, and in the Rajya Sabha by 167 votes to seven. In her own speech, the prime minister invited 'the princes to join the elite of the modern age, the elite which earns respect by its talent, energy and contribution to human progress, all of which can only be done when we work together as equals without regarding anybody as of special status.' " (page 441). 6. Cheesman, David (1997). Landlord power and rural indebtedness in colonial Sind, 1865–1901. London: Routledge. hlm.10–. ISBN978-0-7007-0470-5. Diakses tanggal 6 November 2011.

Once they seemed immutable, invincible. In 1971 they were "derecognized," their privileges, privy purses and titles all abolished at a stroke" (page 91)
