I have read and re-read both 'The Lord of the Rings' and the 'Harry Potter' series many times over. And I began thinking there were a lot of comparisons in both classics.
I will begin with Frodo and Harry. They were both orphans. Frodo was raised by his Uncle Bilbo and Harry was raised by his Aunt Petunia and Uncle Vernon. Frodo was despised by the Sack-Ville Bagginses, and Harry was despised by the Dursleys.
Both Frodo and Harry were hunted by a Dark Lord. Frodo was hunted by Sauron, and Harry was hunted by Lord Voldemort. Both were called the Dark Lord.
Frodo had The Ring which connected him to the evil of the Dark Lord. The Ring drew the Ring Wraiths better know as the Nazguls who followed the whereabouts of The Ring. Harry on the other hand had a scar left by Lord Voldemort which was a direct connection to the Dark Lord, as we all know it was a part of the Dark Lord's soul that resided in side of Harry. It was an evil connection that Harry felt when the Dark Lord was feeling most evil or was committing an evil act.
There was Gandalf in 'The Lord of the Rings' and there was Dumbledore in 'Harry Potter'. Both were very great wizards. Gandalf protected Frodo and knew of Frodo's whereabouts due to the fact that Gandalf wore one of the elf rings Naria, which made a direct connection to The One Ring of power. Dumbledore suspected that there was more to Harry's scar then met the eye, and he knew he had to protect Harry to help him survive the onslaught of the Dark Lord.'
Frodo had his companions from the shire to be with him on his journey and to sustain him in times of need. But especially Samwise was his faithful companion to the end. In Harry's case, he had Ron and Hermoine to help him figure out how to get rid of parts of Voldemort's soul which were hidden in horcruxes in various valuable treasures from the Dark Lord's wizard family, or from past Hogwart's founders.
Frodo had things to protect him from the Dark Lord or other hideous creatures who fought to kill him. Frodo had the mithril coat that Bilbo had given him, he also has Sting, the sword to protect him, and he had Lady Galadriel's phial, a crystal light that kept evil and darkness away when Frodo was in dangerous places.
The sword of Goderic Griffindor came to Harry in the Chamber of Secrets to protect him along with Fawkes the Phoenix. Harry's own wand protected him too, at times as it shared the same core as the Dark Lord's so Harry was not as easy to kill as Voldemort found out. Harry, in the end, had the Deathly Hallows to protect him...the Resurrection Stone, The Elder Wand, and the Cloak of Invisibility.
Frodo could make himself invisible by wearing The One Ring but with much risk to his own safety as it would bring the Nazgul to him. But it did hide him from Boromir when he sought to take the ring from Frodo. Whereas, Harry had his invisibility cloak to protect him from danger at times.
The dementors could suck the soul out of a person, and a few times Harry was attacked by them, but escaped by his own daring. Where as the Nazgul were drawn to Frodo and they too could have taken Frodo to an other worldly realm where Frodo could not have escaped the Dark Lord.
There were the eagles who came at Gandalf's call to help in time of need. The thestrals in Harry Potter also helped the Order of the Phoenix help take Harry to safety.
Then there was Gollum, he was evil yet good, lured by the One Ring which he could not escape the agony of it's pull on him. Gollum 'came' with the ring of power. Frodo had no choice but to grudgingly 'befriend' him. There was Dobby who helped Harry and Kreacher who despised Harry but was bound to him out of the death of Sirius Black...Harry 'inherited' Kreacher and as Frodo, Harry grudgingly 'befriended' him.
Then there was Saurman, the great wizard who turned bad, but was enticed by the plantir which was a direct link to the Dark Lord and Sauman's mind was corrupted by deceit. If not for that, he would have survived the Dark Lord's power over him. Then you have Snape, who was by all means the most difficult character to figure out as he seemed to despise Harry with a hate/love relationship only because he had loved Lilly Evans who was Harry's mother.
That is not all of the comparisons I found, but that will do for a while. Both book series are some of the greatest classics written of all time. Founded on faith and trust, and the ultimate evil being finally overcome of good, with much risk of defeat or failure, but the stout hearts of Frodo and Harry won out in the end.
Thank you for reading my own synopsis of my favorite books.
