Name the King of Tripura who conferred upon Rabindranath Tagore the title of…

Princely-state rulers who patronised Rabindranath Tagore and Visva-Bharati sometimes marked milestone occasions — birthdays, anniversaries, state visits — by conferring an honorary title on him. Identifying WHO conferred a specific title requires matching that ruler's own reign dates to the exact occasion, not just any historical association between his royal house and Tagore.

Tagore's ties with the Tripura royal family spanned several reigns and several separate honours, but the title "Bharat Bhaskar" was conferred on one specific, well-documented occasion: around Tagore's 80th birthday in 1941, only weeks before his death. Per the Tripura state government's own historical record, the reigning Maharaja credited with this conferral was Bir Bikram Manikya (reigned 1923–1947), Tripura's last ruling Maharaja.

Why the other kings do not fit:

• Maharaja Bir Chandra Manikya (reigned c. 1862–1896): actually the FIRST Tripura ruler to honour Tagore — he sent an emissary to confer the title "Great Poet" on a then-unknown, young Tagore in 1882 — but that was a separate, much earlier honour; his reign ended decades before the 1941 "Bharat Bhaskar" conferral.

• Maharaja Radha Kishore Manikya (reigned 1896–1909): a genuine personal friend and literary correspondent of Tagore, which is why this option is a common trap — but his reign, too, had ended long before the 1941 occasion.

• Maharaja Dhanya Manikya: ruled Tripura in the 16th century, centuries before Tagore was even born — no interaction between the two is historically possible.

Only Bir Bikram Manikya's reign overlaps the 1941 event — the other three kings each belong to a different, non-overlapping chapter of the Tripura-Tagore relationship — so he is the king who conferred "Bharat Bhaskar" on Rabindranath Tagore.
