Any connection between -dom (kingdom) and dharma?

Appreciated the article on the derivation of -dom as in kingdom; any relationship between that and dharma? I see that -dom goes back to Old English for doom, judgment, law statute, and dharma goes back to Proto-Indo-Iranian root *dhar- ("to fasten, to support, to hold") (see http://en.wikipedia.org/wiki/Dharma), but was wondering if OE traces back to that as well.

There appears to be no relationship between -dom and dharma. There is, however, a definite etymological connection between -dom and dhama, as well as dhaman (the middle a is pronounced as [-aa-], as in father, in the case of these latter two sanskrit words).

The Sanskrit word dhaman literally means dwelling-place, house, abode, domain. By extension it is rarely taken to mean law, rule or order but is etymologically distinct from dharma. It is cognate with the German tuom, Greek themis, Latin fam-ulus and Anglosaxon dom. The Proto-Germanic cognate is domaz, originating from the PIE root dhe meaning placing, putting, holding, possessing, having.

Sanskrit dharma means that which is established or firm, steadfast – and is derived from dhara and the PIE root dhri meaning bearing, supporting (soil, the world - and therefore earth, womb). This word does not have a cognate in the English Language, Greek or Latin.

Just as the German word sittlichkeit, related in meaning to dharma somewhat, does not have a direct link to any corresponding English word.
