"On 28 June 1914, Archduke Franz Ferdinand of Austria, heir to the Austro-Hungarian throne, and his wife, Sophie, Duchess of Hohenberg, were shot dead (while traveling in an open-topped car) in Sarajevo, capital of Bosnia and Herzegovina, by Gavrilo Princip, one of a group of six assassins coordinated by Danilo Ilić" -> a bit of a run-on sentence

• "At the top of these Serbian military conspirators..." - Serbian military conspirators have not previously been referred to, unless you mean the assassins, in which case this should be made clear
• "underground railroad" - two issues here. First, it is referred to both as a railroad and a railway - should be consistent. Second, the term is unclear and should be explained on its first occurence - it's not an actual underground railroad, but a network of people that operate secretly for some purpose.

"French Occupied Salonika" -> "French-occupied Salonika" with Salonika linked

• An evidential approach must be taken to weed through the various claims and counter-claims concerning responsibility. - this phrase is unencyclopedic, in my opinion

as a fully sovereign state, as the Kingdom of Serbia - remove second "as"

• "These disputes included a customs dispute (parallelism) with Austria-Hungary beginning in 1906 (commonly referred to as the "Pig War" as pigs were Serbia's major export to Austria-Hungary), the Bosnian crisis of 1908–1909 where Serbia assumed an attitude of protest over Austria-Hungary's annexation of Bosnia-Herzegovina (ending in a Serbian climb-down (meaning?) in March 1909), and finally the two Balkan wars of 1912–1913 where Serbia conquered Macedonia and Kosovo, taking these provinces from the Ottoman Empire and Bulgaria."
• There are many run-on sentences throughout the article that need to be fixed
• The chronology in "Background" and "Preliminaries" is scrambled at times
• Locations should be linked on first appearance (Belgrade, Toulouse, etc)
• "Agreement in principle" - what does this mean?

"under the grounds" -> "on the grounds"

• "a war against Serbia" - isn't the Black Hand on the same side as Serbia?

Inline citations should be after punctuation

"continue with plan for the assassination" - grammar

"grossly amateurs" - grammar

"the intention was provide for" - grammar

"The Serbian Prime Minister Pasic at the beginning of June 1914" - switch

• "they handed the small card to Captain Popović" - what card?

Be consistent in the way dates are formatted - either "28 May" or "May 28", not both

Dates are generally not linked unless the topic of the page being linked to is germane to the topic at hand

• "and link back up" - meaning?
• "On the morning of 30 May Prvanović's revenue sergeants assembled and Sergeant Budivoj Grbić accepted the task and led Princip and Grabež with the weapons by foot to Isaković’s Island, a small island in the middle of the Drina River that separated Serbia from Bosnia." - grammar + clarity
• Austro-Hungarian Redbook - what is this?

Nikola Pašić - is this the same person referred to earlier as "Pasic"?

Need consistency in names - Pasic vs Pašić, Grabež vs Grabez, Franz Ferdinand vs Franz-Ferdinand, etc

"encouraging them to bravery" - grammar

"After mass" -> "After Mass"

" - that the assassination had been unsuccessful - " - use en-dashes instead of hyphens

"Conspiracy to commit high treason carried a maximum sentence of death which conspiracy to commit simple murder did not" - grammar

In the table of sentences, why do some use curly brackets and others parantheses?

• The paragraph under the table says that only two died of TB in prison, while the table claims three
• "denies that Russia had one single agent in Serbia at the time" - does that mean that they had no agents or many agents?
• "high words" - meaning?
• "accepting points #8 and #10" - since the points are not enumerated here, you should describe the points referred to instead of simply numbering them

Choose either "20th century" or "twentieth century", not both

• The 14th anniversary of the morganatic oath fell on 28 June and they were happy to celebrate it far from Vienna

• Due to a mistake, three local police officers got into the first car with the chief officer of special security; the special security officers who were supposed to accompany their chief got left behind.
• The procession sped away towards the Town Hall leaving the disabled car behind. Cvjetko Popović, Gavrilo Princip and Trifun Grabež failed to act as the motorcade passed them at high speed.
• The only obvious measure taken was for Count Harrach to take up a protective position on the left hand running board of the car. This is confirmed by photographs of the scene outside the Town Hall.

• Cabrinović, though, began placing some blame on people in Serbia.
