Bhutan's monarchy was established in 1907 by a unanimous vote. How and why did that consensus happen?
Bhutan's monarchy seems like an interesting outlier; it was a constitutional monarchy from the beginning, it was established in the 20th century, it has explicit provisions for removing a king from office, and includes a requirement of being a protector of all religions despite being an explicitly Buddhist role. So, what led to such an unusual monarchy arising in 1907, and how did the first king get consensus to form the monarchy?
