Mars is the traditional ruling planet of the first house, because the house is associated with the first sign of the zodiac, Aries. Representing life-force, activity and the struggle to survive and conquer, Mars is creating a highly energetic and dynamic personality when located in the house of self. This is a great position for the red planet to reside in, even if the abundance of energy can lead to aggressive behaviors and other trouble caused by rash. The native with Mars in the 1st house yearns for independence and is quite straightforward. Life is always a battle, and for planet Mars, there is no other outcome than victory. Individuals with such an aspect are spontaneous, which can lead to difficulties due to inconsideration of all the parameters of situations.
Mars represents action, energy, way of acting, struggle, fighting spirit, etc…
In this 1st House, Mars will therefore be dominant, especially if it is close to the tip of the Ascendant, and means that the person will be active, dynamic (regardless of the sign), and therefore will not hesitate to take initiatives in order to achieve self-fulfilment.
The important thing for her will therefore be more to act than to suffer, and who will be able to appreciate the challenges, or at least the fact of having specific objectives to achieve. If Mars is in a very strong position, action will tend to dominate, sometimes to the detriment of reason (see Mercury’s position of course).
The aspects concerning Mars will be important, because with harmonious aspects, the person will tend to act in a loyal, constructive way, while knowing how to adapt to the objectives to be achieved. The behavior will generally be fairly well controlled. On the other hand, with dissonant aspects, the energy risks being poorly controlled, the behavior harder, authoritarian, sometimes aggressive, not very adaptable, etc… hence the risk of confrontations, especially with others, since Mars is in the axis of houses I and VII (relationships with others). It should be noted that Mars in House 1, especially badly apected, will have a role to play in terms of health (see sign and aspects).
As for the other planets, two cases can arise:
– Mars in 1st House is in the same sign as the Ascendant, in which case there will be harmony between the way of reacting and the image one gives to others, and the way of acting, and therefore no surprises for the others.
– Mars in 1st House is in a different sign from the Ascendant, there may be a gap between reactions and action in particular. Imagine an Aquarius Ascendant and Mars in Pisces. With this Ascendant the person will tend to react in a rather emotional and impulsive way (the ruler is Uranus), but with Mars in Pisces, the action will not necessarily follow immediately, because it will be more adaptable and will tend to undergo a little before deciding, and the action may be different from what people expect. So between reactive behavior and taking action, things will surely be more complicated to manage. We can have the opposite reasoning with a Pisces Ascendant and a Mars in Aries.
