Charles Louis died in 1680, and Rupert did not cherish the enmity he had borne him beyond the grave. On the contrary, he was anxious to do what he could for the benefit of his impecunious nephews and nieces. For Carellie he did not care, the young Elector had offended him by his neglect,[27] but it was not Carellie who needed his protection; it was rather against Carellie that he took up the cause of the Raugraefen, as Charles Louis' children by Louise were called. The circumstances of the case had left them completely dependent on their eldest brother, who bore them no great love. This was not due to the fact that their mother had supplanted his own. Carellie had never loved his mother; he had often told his father that he paid no heed to what Charlotte might say, and had himself urged her to consent to a divorce.[28] But he was of a peculiar temperament, jealous, fretful, difficult, and his dislike of the Raugraefen was really due, partly to the influence of his disagreeable wife, and partly to jealousy of the affection which his father had always shown to them, especially to Moritzien,--poor Moritzien, gifted with all the Palatine fascination and brilliancy, but ruined by a life of uninterrupted indulgence, so that he drank himself to death. Promises of providing for these cadets had been wrung from Carellie by his anxious father, but these promises he showed himself in no haste to keep, and Sophie appealed, on their behalf to Rupert. He showed himself ready to assist them, and demanded a concise account of the whole {355} busiess, in order that he might be qualified to interfere.[29] "Not that he thinks the Elector will break his sacred promise to his father,"[30] declared Sophie. Nevertheless she urged the eldest Raugraf, Karl Ludwig, or "Carllutz," who had shortly before visited Rupert in England, to write very affectionately to his uncle, in gratitude for the interest shown in them.[31] But, unfortunately for the Raugraefen, Rupert did not long survive his brother; and only a few months later Sophie wrote to one of her nieces: "You have lost a great friend in my brother Prince Rupert. I am very much troubled and overwhelmed with the unexpected loss. I know the Electress Dowager will also bewail him."[32]
