Suddiya HG 1

Sadiya is a town in Tinsukia district, Assam, in India. It was the capital of the Chutia Kingdom but after the downfall of the kingdom, the Ahoms administered it through the Sadiyakhowa Gohain. Extensive remains of buildings and fortifications built during the Chutia rule near Sadiya point to the importance of the region in the past. Historically Sadiya or Sadhaya referred to the Chutia kingdom, Sadhayapura (preasent-day Sadiya) being its capital. It is claimed to be the center of development of the eastern Assamese dialects. Its stands on a grassy plain, almost surrounded by forested Himalayan mountains, on the right bank of Lohit River which is locally (but erroneously) considered the main stream of the Brahmaputra River. The deepest point of the Brahmaputra River is located near this region. It is famous for a flower named satphul (the word means "blessing" or a "desert flower"), which is much like Jasmine.

Suddiya HG 1 is a pre-1854 handstruck postal marking of the post office at Suddiya — the present-day Sadiya — in the Bengal Presidency, British India, recorded in use around 1840. Known strikes are in red. Its "HG 1" designation is the figure number assigned in the Hammond Giles catalogue of the handstruck postage stamps of India.

A single surviving cover bearing this mark is recorded in the census, with images and provenance. On the strength of that count the mark is graded "1 example recorded" — the grade moves automatically as new covers are recorded. Collectors searching for suddiya pre stamp covers, suddiya postal history or "Suddiya HG1" material can compare HG 1 across every office or browse the rest of the Suddiya marks.
