Grahas in Kendra have certain Sakti

Chapter 7 of Phaladeepika - First Shaloka

•  if he has three or more planets in their signs of exaltation or in their own signs posited in a kendra (without FTW)
•  Even one born in an ordinary family becomes a ruler of the earth possessing bands of elephants and horses, if five or more planets be posited in a kendra in their signs of exaltation or in their own sign*.

Shloka 48 Raj Yoga chapter in BPHS - Last Shaloka

48. If all benefics are relegated to Kendras, while malefics are in 3rd, 6th and 11th House, the native, though may be of mean descent, will ascend the throne.

Why the last yoga is important. Upkarma/Upsamhara (introduction and conclusion).

Benefics in Kendra:

BPHS - Chapter 7

21. If 10ths Lord, placed in his own House, or in its exaltation Rāśi, gives a Aspect to Lagna, a Raja Yoga is formed. Similar is the case, if benefics are in Kendras.

•  simplified way of reading (if the 10th lord is placed in his own house or in exaltation, aspect the ascendant is a raj yoga)

47. Even, if one among Jupiter, Venus and Mercury is in exaltation, while a benefic is in a Kendr, the native will become a king, or be equal to him. (note this does not require exalted one in Kendra)

• simplified way of reading (any of the natural benefic -JP, VE, ME exalted while another natural benefic is in lagna. Note this does not require exalted one in lagna

11. One will be related to royal circles, if Venus is the Karakāńś, or in the 5th there from, or in Lagna, or in Arudh Lagna, receiving a Aspect from, or conjunct with Jupiter, or Moon

•  simplified way of reading - Venus in Uday Lagna, associated or aspected by Jupiter or Moon

Phaladeepika - Chpter 7 vs 20

20. Four Yogas are described in this Verse which are as follows —

 (a) If Venus is aspected by Jupiter a person born in a royal family becomes a King.
(b) If Jupiter occupies a sign other than Capricorn identical with Lagna, the native becomes a King with many elephants under his charge. (that is Jupiter in Lagna but not in Capricorn)

(c) A King will be born if in a nativity the lord of the Lagna vested with full strength occupies a Kendra. (that is faultless strong lagna lord in Kendra)

 (d) If at birth Mercury with full strength is posited in Kendra and is aspected by Jupiter, the native becomes so influential that the Kings act according to his advice. (That is faultless strong Mercury in Kendra aspected by Jupiter) - Shudh Bhuddhi

BPHS Chapter 7

9-10. Should there be benefics in the 2nd, the 4th and the 5th, counted either from Lagnas Lord, or from Atma Karak Rāśi, one will become a king. Similarly malefics in the 3rd and 6th from Lagnas Lord, or from Atma Karak Rāśi will make one a king.

17. If Lagna, 2nd and 4th House are occupied by benefics, while a malefic is in 3rd House, one will become a king, or equal to a king.

Phal Deepika  - Chapter 7 Vs 24

 Malefics posited in the 3rd, 6th and 11th house counted from. The house occupied by the lord of Lagna, Moon or from the Lagna.

BPHS - Chapter 7

Vs 10 Similarly malefics in the 3rd and 6th from Lagnas Lord, or from Atma Karak Rāśi will make one a king.

Yogas Organized around the Moon

Phal Depika - Chapter 7 vs 7

When at birth the Moon is brilliant with white luster and is aspected by planet disposed in his own sign or his sign of exaltation, even the person whose legitimacy is questionable, will become a king.

that is full moon aspected by a swa or exalted grah

Phal Deepika - chapter 7 

22. There are again two Raja Yogas in this verse as described below: — (1) Should the Moon with full rays be in Pisces aspected by a friendly planet, the native will become a king with pre-eminent position and delighting the world. (2) Should the Moon be full and be in his sign of exaltation the native will become a very generous, charitable and praiseworthy King.

11. If the Moon brilliant with disc resembling nectar and lotus stalk in color (i.e. the full Moon) occupies a Navamsa owned by the Sun and benefics unassociated with malefics occupy kendra, the person born will become a king owning many elephants

BPHS Chapter 7

44. If one, or two, or three Planets are in exaltation, one of a royal scion will become a king, while another will be equal to a king, or be wealthy.

45. If four, or five Planets occupy their exaltation Rāśis, or Moolatrikona Rāśis, even a person of base birth will become king.

Phal Deepika - 

3. Even a single planet, even if he be in debilitation, is capable of making a person equal to a king, if not being posited in Dusthana (6th. 8th or 12th) or combust and be possessed of brilliant rays and be in retrograte motion. If three or more planets be so disposed, the native becomes a king. If there are many planets posited in auspicious houses and Navamsas. the native will become a king endowed with the inslgnias of royalty such as crown, umbrella and waving chowries. Check in multiple amsas.

4. The native belonging to royal family becomes victorious every where if at his birth two or more planets are endowed with Digbala.
