Mars rules houses 1 and 8 for Aries rising — lagna lord — benefic. The rules behind that verdict, dasha themes and how it compares with the other planets.
✦ Generate My Free Birth ChartFor Aries rising, Mars is the lagna lord, which the classics treat as auspicious whatever else it rules. It rules Aries (the 1st house) and Scorpio (the 8th house), so its Mahadasha (7 years) concentrates on self, health and vitality and transformation, longevity and sudden events.
Each rule below is applied in turn; the verdict is the sum. Positive numbers support the planet, negative ones weigh against it.
| Rule applied | Weight |
|---|---|
| Aries is the 1st house (Lagna (self)); Aries is Mars's moolatrikona sign, so it counts 1.5× | +3.0 |
| Scorpio is the 8th house (Dusthana) | -2.5 |
| Net score → Lagna Lord — Benefic | +0.50 |
Aries — house 1 (Lagna (self)). The 1st house governs self, health and vitality. Whatever Mars promises or withholds in a chart tends to be delivered through these matters. It is also the planet's moolatrikona sign.
Scorpio — house 8 (Dusthana). The 8th house governs transformation, longevity and sudden events. Whatever Mars promises or withholds in a chart tends to be delivered through these matters.

Rahu and Ketu own no signs, so they have no lordship to classify; they act through the sign lord of the sign they occupy and the planets they join (see Rahu & Ketu in KP).
In the Vimshottari system Mars's Mahadasha lasts 7 years out of the 120-year cycle. For Aries rising it activates the 1st house (self, health and vitality) and the 8th house (transformation, longevity and sudden events). A well-supported period therefore tends to lift those areas; the sub-lords of the period and the transits at the time decide which way it actually goes. See Mars Mahadasha for the period itself.
Aries is a movable sign, so its Badhaka (obstruction) house is the 11th, whose sign is Aquarius and whose lord is Saturn. Mars is not the Badhaka lord. The Maraka lords for Aries rising are Venus (2nd) and Venus (7th); Mars is not one of them.
In KP astrology, ruling a house by sign is only the weakest of the four levels a planet can signify through (the others are occupying it and the star-lord links). A lagna lord — benefic reading by lordship is useful context, but the sub-lord chain in the actual chart is what decides outcomes. See Significators in KP and Sub-Lord Theory.
