Mars rules 5th and 12th house is in 11th house in Libra

When Mars is placed in the 11th house in Libra sign, it can bring a combination of positive and challenging effects on the native's life.

On one hand, Mars signifies courage, energy, and drive, and when it is placed in the 11th house of gains and achievements, it can fuel the native's ambitions and desire for success. The native may have a strong social circle, become a leader among friends, and actively participate in group activities or organizations.

On the other hand, Libra is a sign ruled by Venus, which is Mars' natural enemy. This indicates some tension between the planet of action and the planet of harmony and balance. In this placement, Mars may be tempered by the sign's peaceful and diplomatic qualities, resulting in a tendency of the native to avoid conflict and confrontation.

Additionally, Mars in the 11th house can create a strong desire for material gains and financial success. This can lead to overly aggressive behavior in pursuit of wealth, which may not always be in alignment with the native's ethical and moral values.

Overall, the effects of Mars in the 11th house in Libra sign depend on various factors such as the house lordship, conjunctions, aspects, and the overall strength of Mars in the birth chart. A detailed analysis is necessary to make an accurate prediction for an individual.
